[PATCH] I2C: Move hwmon drivers (3/3)
Part 3: Move the drivers documentation, plus two general documentation files. Note that the patch "adds trailing whitespace", because it does move the files as-is, and some files happen to have trailing whitespace.

-Description
------------
-
-The chips supported by this driver are very similar. The Maxim MAX1617 is
-the oldest; it has the problem that it is not very well detectable. The
-MAX1617A solves that. The ADM1021 is a straight clone of the MAX1617A.
-Ditto for the THMC10. From here on, we will refer to all these chips as
-ADM1021-clones.
-
-The ADM1021 and MAX1617A reports a die code, which is a sort of revision
-code. This can help us pinpoint problems; it is not very useful
-otherwise.
-
-ADM1021-clones implement two temperature sensors. One of them is internal,
-and measures the temperature of the chip itself; the other is external and
-is realised in the form of a transistor-like device. A special alarm
-indicates whether the remote sensor is connected.
-
-Each sensor has its own low and high limits. When they are crossed, the
-corresponding alarm is set and remains on as long as the temperature stays
-out of range. Temperatures are measured in degrees Celsius. Measurements
-are possible between -65 and +127 degrees, with a resolution of one degree.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared!
-
-This driver only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values. It is possible to make
-ADM1021-clones do faster measurements, but there is really no good reason
-for that.
-
-Xeon support
-------------
-
-Some Xeon processors have real max1617, adm1021, or compatible chips
-within them, with two temperature sensors.
-
-Other Xeons have chips with only one sensor.
-
-If you have a Xeon, and the adm1021 module loads, and both temperatures
-appear valid, then things are good.
-
-If the adm1021 module doesn't load, you should try this:
- modprobe adm1021 force_adm1021=BUS,ADDRESS
- ADDRESS can only be 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e.
-
-If you have dual Xeons you may have appear to have two separate
-adm1021-compatible chips, or two single-temperature sensors, at distinct
-addresses.

-Description
------------
-
-(This is from Analog Devices.) The ADM1025 is a complete system hardware
-monitor for microprocessor-based systems, providing measurement and limit
-comparison of various system parameters. Five voltage measurement inputs
-are provided, for monitoring +2.5V, +3.3V, +5V and +12V power supplies and
-the processor core voltage. The ADM1025 can monitor a sixth power-supply
-voltage by measuring its own VCC. One input (two pins) is dedicated to a
-remote temperature-sensing diode and an on-chip temperature sensor allows
-ambient temperature to be monitored.
-
-One specificity of this chip is that the pin 11 can be hardwired in two
-different manners. It can act as the +12V power-supply voltage analog
-input, or as the a fifth digital entry for the VID reading (bit 4). It's
-kind of strange since both are useful, and the reason for designing the
-chip that way is obscure at least to me. The bit 5 of the configuration
-register can be used to define how the chip is hardwired. Please note that
-it is not a choice you have to make as the user. The choice was already
-made by your motherboard's maker. If the configuration bit isn't set
-properly, you'll have a wrong +12V reading or a wrong VID reading. The way
-the driver handles that is to preserve this bit through the initialization
-process, assuming that the BIOS set it up properly beforehand. If it turns
-out not to be true in some cases, we'll provide a module parameter to force
-modes.
-
-This driver also supports the ADM1025A, which differs from the ADM1025
-only in that it has "open-drain VID inputs while the ADM1025 has on-chip
-100k pull-ups on the VID inputs". It doesn't make any difference for us.

-
-
-Description
------------
-
-This driver implements support for the Analog Devices ADM1026. Analog
-Devices calls it a "complete thermal system management controller."
-
-The ADM1026 implements three (3) temperature sensors, 17 voltage sensors,
-16 general purpose digital I/O lines, eight (8) fan speed sensors (8-bit),
-an analog output and a PWM output along with limit, alarm and mask bits for
-all of the above. There is even 8k bytes of EEPROM memory on chip.
-
-Temperatures are measured in degrees Celsius. There are two external
-sensor inputs and one internal sensor. Each sensor has a high and low
-limit. If the limit is exceeded, an interrupt (#SMBALERT) can be
-generated. The interrupts can be masked. In addition, there are over-temp
-limits for each sensor. If this limit is exceeded, the #THERM output will
-be asserted. The current temperature and limits have a resolution of 1
-degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute) but measured
-in counts of a 22.5kHz internal clock. Each fan has a high limit which
-corresponds to a minimum fan speed. If the limit is exceeded, an interrupt
-can be generated. Each fan can be programmed to divide the reference clock
-by 1, 2, 4 or 8. Not all RPM values can accurately be represented, so some
-rounding is done. With a divider of 8, the slowest measurable speed of a
-two pulse per revolution fan is 661 RPM.
-
-There are 17 voltage sensors. An alarm is triggered if the voltage has
-crossed a programmable minimum or maximum limit. Note that minimum in this
-case always means 'closest to zero'; this is important for negative voltage
-measurements. Several inputs have integrated attenuators so they can measure
-higher voltages directly. 3.3V, 5V, 12V, -12V and battery voltage all have
-dedicated inputs. There are several inputs scaled to 0-3V full-scale range
-for SCSI terminator power. The remaining inputs are not scaled and have
-a 0-2.5V full-scale range. A 2.5V or 1.82V reference voltage is provided
-for negative voltage measurements.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that in the current implementation, all hardware
-registers are read whenever any data is read (unless it is less than 2.0
-seconds since the last update). This means that you can easily miss
-once-only alarms.
-
-The ADM1026 measures continuously. Analog inputs are measured about 4
-times a second. Fan speed measurement time depends on fan speed and
-divisor. It can take as long as 1.5 seconds to measure all fan speeds.
-
-The ADM1026 has the ability to automatically control fan speed based on the
-temperature sensor inputs. Both the PWM output and the DAC output can be
-used to control fan speed. Usually only one of these two outputs will be
-used. Write the minimum PWM or DAC value to the appropriate control
-register. Then set the low temperature limit in the tmin values for each
-temperature sensor. The range of control is fixed at 20 °C, and the
-largest difference between current and tmin of the temperature sensors sets
-the control output. See the datasheet for several example circuits for
-controlling fan speed with the PWM and DAC outputs. The fan speed sensors
-do not have PWM compensation, so it is probably best to control the fan
-voltage from the power lead rather than on the ground lead.
-
-The datasheet shows an example application with VID signals attached to
-GPIO lines. Unfortunately, the chip may not be connected to the VID lines
-in this way. The driver assumes that the chips *is* connected this way to
-get a VID voltage.

-
-Interface
----------
-The I2C addresses listed above assume BIOS has not changed the
-chip MSB 5-bit address. Each chip reports a unique manufacturer
-identification code as well as the chip revision/stepping level.
-
-Description
------------
-[From ADM9240] The ADM9240 is a complete system hardware monitor for
-microprocessor-based systems, providing measurement and limit comparison
-of up to four power supplies and two processor core voltages, plus
-temperature, two fan speeds and chassis intrusion. Measured values can
-be read out via an I2C-compatible serial System Management Bus, and values
-for limit comparisons can be programmed in over the same serial bus. The
-high speed successive approximation ADC allows frequent sampling of all
-analog channels to ensure a fast interrupt response to any out-of-limit
-measurement.
-
-The ADM9240, DS1780 and LM81 are register compatible, the following
-details are common to the three chips. Chip differences are described
-after this section.
-
-
-Measurements
-------------
-The measurement cycle
-
-The adm9240 driver will take a measurement reading no faster than once
-each two seconds. User-space may read sysfs interface faster than the
-measurement update rate and will receive cached data from the most
-recent measurement.
-
-ADM9240 has a very fast 320us temperature and voltage measurement cycle
-with independent fan speed measurement cycles counting alternating rising
-edges of the fan tacho inputs.
-
-DS1780 measurement cycle is about once per second including fan speed.
-
-LM81 measurement cycle is about once per 400ms including fan speed.
-The LM81 12-bit extended temperature measurement mode is not supported.
-
-Temperature
------------
-On chip temperature is reported as degrees Celsius as 9-bit signed data
-with resolution of 0.5 degrees Celsius. High and low temperature limits
-are 8-bit signed data with resolution of one degree Celsius.
-
-Temperature alarm is asserted once the temperature exceeds the high limit,
-and is cleared when the temperature falls below the temp1_max_hyst value.
-
-Fan Speed
----------
-Two fan tacho inputs are provided, the ADM9240 gates an internal 22.5kHz
-clock via a divider to an 8-bit counter. Fan speed (rpm) is calculated by:
-
-rpm = (22500 * 60) / (count * divider)
-
-Automatic fan clock divider
-
- * User sets 0 to fan_min limit
- - low speed alarm is disabled
- - fan clock divider not changed
- - auto fan clock adjuster enabled for valid fan speed reading
-
- * User sets fan_min limit too low
- - low speed alarm is enabled
- - fan clock divider set to max
- - fan_min set to register value 254 which corresponds
- to 664 rpm on adm9240
- - low speed alarm will be asserted if fan speed is
- less than minimum measurable speed
- - auto fan clock adjuster disabled
-
- * User sets reasonable fan speed
- - low speed alarm is enabled
- - fan clock divider set to suit fan_min
- - auto fan clock adjuster enabled: adjusts fan_min
-
- * User sets unreasonably high low fan speed limit
- - resolution of the low speed limit may be reduced
- - alarm will be asserted
- - auto fan clock adjuster enabled: adjusts fan_min
-
- * fan speed may be displayed as zero until the auto fan clock divider
- adjuster brings fan speed clock divider back into chip measurement
- range, this will occur within a few measurement cycles.
-
-Analog Output
--------------
-An analog output provides a 0 to 1.25 volt signal intended for an external
-fan speed amplifier circuit. The analog output is set to maximum value on
-power up or reset. This doesn't do much on the test Intel SE440BX-2.
-
-Voltage Monitor
-
-Voltage (IN) measurement is internally scaled:
-
- nr label nominal maximum resolution
- mV mV mV
- 0 +2.5V 2500 3320 13.0
- 1 Vccp1 2700 3600 14.1
- 2 +3.3V 3300 4380 17.2
- 3 +5V 5000 6640 26.0
- 4 +12V 12000 15940 62.5
- 5 Vccp2 2700 3600 14.1
-
-The reading is an unsigned 8-bit value, nominal voltage measurement is
-represented by a reading of 192, being 3/4 of the measurement range.
-
-An alarm is asserted for any voltage going below or above the set limits.
-
-The driver reports and accepts voltage limits scaled to the above table.
-
-VID Monitor
------------
-The chip has five inputs to read the 5-bit VID and reports the mV value
-based on detected CPU type.
-
-Chassis Intrusion
------------------
-An alarm is asserted when the CI pin goes active high. The ADM9240
-Datasheet has an example of an external temperature sensor driving
-this pin. On an Intel SE440BX-2 the Chassis Intrusion header is
-connected to a normally open switch.
-
-The ADM9240 provides an internal open drain on this line, and may output
-a 20 ms active low pulse to reset an external Chassis Intrusion latch.
-
-Clear the CI latch by writing value 1 to the sysfs chassis_clear file.
-
-Alarm flags reported as 16-bit word
-
- bit label comment
- --- ------------- --------------------------
- 0 +2.5 V_Error high or low limit exceeded
- 1 VCCP_Error high or low limit exceeded
- 2 +3.3 V_Error high or low limit exceeded
- 3 +5 V_Error high or low limit exceeded
- 4 Temp_Error temperature error
- 6 FAN1_Error fan low limit exceeded
- 7 FAN2_Error fan low limit exceeded
- 8 +12 V_Error high or low limit exceeded
- 9 VCCP2_Error high or low limit exceeded
- 12 Chassis_Error CI pin went high
-
-Remaining bits are reserved and thus undefined. It is important to note
-that alarm bits may be cleared on read, user-space may latch alarms and
-provide the end-user with a method to clear alarm memory.

-Description
------------
-
-This driver implements support for the Asus ASB100 and ASB100-A "Bach".
-These are custom ASICs available only on Asus mainboards. Asus refuses to
-supply a datasheet for these chips. Thanks go to many people who helped
-investigate their hardware, including:
-
-Vitaly V. Bursov
-Alexander van Kaam (author of MBM for Windows)
-Bertrik Sikken
-
-The ASB100 implements seven voltage sensors, three fan rotation speed
-sensors, four temperature sensors, VID lines and alarms. In addition to
-these, the ASB100-A also implements a single PWM controller for fans 2 and
-3 (i.e. one setting controls both.) If you have a plain ASB100, the PWM
-controller will simply not work (or maybe it will for you... it doesn't for
-me).
-
-Temperatures are measured and reported in degrees Celsius.
-
-Fan speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit.
-
-Voltage sensors (also known as IN sensors) report values in volts.
-
-The VID lines encode the core voltage value: the voltage level your
-processor should work with. This is hardcoded by the mainboard and/or
-processor itself. It is a value in volts.
-
-Alarms: (TODO question marks indicate may or may not work)
-
-0x0001 => in0 (?)
-0x0002 => in1 (?)
-0x0004 => in2
-0x0008 => in3
-0x0010 => temp1 (1)
-0x0020 => temp2
-0x0040 => fan1
-0x0080 => fan2
-0x0100 => in4
-0x0200 => in5 (?) (2)
-0x0400 => in6 (?) (2)
-0x0800 => fan3
-0x1000 => chassis switch
-0x2000 => temp3
-
-Alarm Notes:
-
-(1) This alarm will only trigger if the hysteresis value is 127C.
-I.e. it behaves the same as w83781d.
-
-(2) The min and max registers for these values appear to
-be read-only or otherwise stuck at 0x00.
-
-TODO:
-* Experiment with fan divisors > 8.
-* Experiment with temp. sensor types.
-* Are there really 13 voltage inputs? Probably not...
-* Cleanups, no doubt...

-Module Parameters
-------------------
-
-* polarity int
- Output's polarity: 0 = active high, 1 = active low
-
-Description
------------
-
-The DS1621 is a (one instance) digital thermometer and thermostat. It has
-both high and low temperature limits which can be user defined (i.e.
-programmed into non-volatile on-chip registers). Temperature range is -55
-degree Celsius to +125 in 0.5 increments. You may convert this into a
-Fahrenheit range of -67 to +257 degrees with 0.9 steps. If polarity
-parameter is not provided, original value is used.
-
-As for the thermostat, behavior can also be programmed using the polarity
-toggle. On the one hand ("heater"), the thermostat output of the chip,
-Tout, will trigger when the low limit temperature is met or underrun and
-stays high until the high limit is met or exceeded. On the other hand
-("cooler"), vice versa. That way "heater" equals "active low", whereas
-"conditioner" equals "active high". Please note that the DS1621 data sheet
-is somewhat misleading in this point since setting the polarity bit does
-not simply invert Tout.
-
-A second thing is that, during extensive testing, Tout showed a tolerance
-of up to +/- 0.5 degrees even when compared against precise temperature
-readings. Be sure to have a high vs. low temperature limit gap of al least
-1.0 degree Celsius to avoid Tout "bouncing", though!
-
-As for alarms, you can read the alarm status of the DS1621 via the 'alarms'
-/sys file interface. The result consists mainly of bit 6 and 5 of the
-configuration register of the chip; bit 6 (0x40 or 64) is the high alarm
-bit and bit 5 (0x20 or 32) the low one. These bits are set when the high or
-low limits are met or exceeded and are reset by the module as soon as the
-respective temperature ranges are left.
-
-The alarm registers are in no way suitable to find out about the actual
-status of Tout. They will only tell you about its history, whether or not
-any of the limits have ever been met or exceeded since last power-up or
-reset. Be aware: When testing, it showed that the status of Tout can change
-with neither of the alarms set.
-
-Temperature conversion of the DS1621 takes up to 1000ms; internal access to
-non-volatile registers may last for 10ms or below.
-
-High Accuracy Temperature Reading
----------------------------------
-
-As said before, the temperature issued via the 9-bit i2c-bus data is
-somewhat arbitrary. Internally, the temperature conversion is of a
-different kind that is explained (not so...) well in the DS1621 data sheet.
-To cut the long story short: Inside the DS1621 there are two oscillators,
-both of them biassed by a temperature coefficient.
-
-Higher resolution of the temperature reading can be achieved using the
-internal projection, which means taking account of REG_COUNT and REG_SLOPE
-(the driver manages them):
-
-Taken from Dallas Semiconductors App Note 068: 'Increasing Temperature
-Resolution on the DS1620' and App Note 105: 'High Resolution Temperature
-Measurement with Dallas Direct-to-Digital Temperature Sensors'
-
-- Read the 9-bit temperature and strip the LSB (Truncate the .5 degs)
-- The resulting value is TEMP_READ.
-- Then, read REG_COUNT.
-- And then, REG_SLOPE.
-
- TEMP = TEMP_READ - 0.25 + ((REG_SLOPE - REG_COUNT) / REG_SLOPE)
-
-Note that this is what the DONE bit in the DS1621 configuration register is
-good for: Internally, one temperature conversion takes up to 1000ms. Before
-that conversion is complete you will not be able to read valid things out
-of REG_COUNT and REG_SLOPE. The DONE bit, as you may have guessed by now,
-tells you whether the conversion is complete ("done", in plain English) and
-thus, whether the values you read are good or not.
-
-The DS1621 has two modes of operation: "Continuous" conversion, which can
-be understood as the default stand-alone mode where the chip gets the
-temperature and controls external devices via its Tout pin or tells other
-i2c's about it if they care. The other mode is called "1SHOT", that means
-that it only figures out about the temperature when it is explicitly told
-to do so; this can be seen as power saving mode.
-
-Now if you want to read REG_COUNT and REG_SLOPE, you have to either stop
-the continuous conversions until the contents of these registers are valid,
-or, in 1SHOT mode, you have to have one conversion made.

-Kernel driver fscher
-====================
-
-Supported chips:
- * Fujitsu-Siemens Hermes chip
- Prefix: 'fscher'
- Addresses scanned: I2C 0x73
-
-Authors:
- Reinhard Nissl <rnissl@gmx.de> based on work
- from Hermann Jung <hej@odn.de>,
- Frodo Looijaard <frodol@dds.nl>,
- Philip Edelbrock <phil@netroedge.com>
-
-Description
------------
-
-This driver implements support for the Fujitsu-Siemens Hermes chip. It is
-described in the 'Register Set Specification BMC Hermes based Systemboard'
-from Fujitsu-Siemens.
-
-The Hermes chip implements a hardware-based system management, e.g. for
-controlling fan speed and core voltage. There is also a watchdog counter on
-the chip which can trigger an alarm and even shut the system down.
-
-The chip provides three temperature values (CPU, motherboard and
-auxiliary), three voltage values (+12V, +5V and battery) and three fans
-(power supply, CPU and auxiliary).
-
-Temperatures are measured in degrees Celsius. The resolution is 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). The value
-can be divided by a programmable divider (1, 2 or 4) which is stored on
-the chip.
-
-Voltage sensors (also known as "in" sensors) report their values in volts.
-
-All values are reported as final values from the driver. There is no need
-for further calculations.
-
-
-Detailed description
---------------------
-
-Below you'll find a single line description of all the bit values. With
-this information, you're able to decode e. g. alarms, wdog, etc. To make
-use of the watchdog, you'll need to set the watchdog time and enable the
-watchdog. After that it is necessary to restart the watchdog time within
-the specified period of time, or a system reset will occur.

-
-Limitations
------------
-
-* Measuring fan speed
-It seems that the chip counts "ripples" (typical fans produce 2 ripples per
-rotation while VERAX fans produce 18) in a 9-bit register. This register is
-read out every second, then the ripple prescaler (2, 4 or 8) is applied and
-the result is stored in the 8 bit output register. Due to the limitation of
-the counting register to 9 bits, it is impossible to measure a VERAX fan
-properly (even with a prescaler of 8). At its maximum speed of 3500 RPM the
-fan produces 1080 ripples per second which causes the counting register to
-overflow twice, leading to only 186 RPM.
-
-* Measuring input voltages
-in2 ("battery") reports the voltage of the onboard lithium battery and not
-+3.3V from the power supply.
-
-* Undocumented features
-Fujitsu-Siemens Computers has not documented all features of the chip so
-far. Their software, System Guard, shows that there are a still some
-features which cannot be controlled by this implementation.

-Description
------------
-
-IMPORTANT:
-
-For the revision 0x00 chip, the in0, in1, and in2 values (+5V, +3V,
-and +12V) CANNOT be read. This is a limitation of the chip, not the driver.
-
-This driver supports the Genesys Logic GL518SM chip. There are at least
-two revision of this chip, which we call revision 0x00 and 0x80. Revision
-0x80 chips support the reading of all voltages and revision 0x00 only
-for VIN3.
-
-The GL518SM implements one temperature sensor, two fan rotation speed
-sensors, and four voltage sensors. It can report alarms through the
-computer speakers.
-
-Temperatures are measured in degrees Celsius. An alarm goes off while the
-temperature is above the over temperature limit, and has not yet dropped
-below the hysteresis limit. The alarm always reflects the current
-situation. Measurements are guaranteed between -10 degrees and +110
-degrees, with a accuracy of +/-3 degrees.
-
-Rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. In
-case when you have selected to turn fan1 off, no fan1 alarm is triggered.
-
-Fan readings can be divided by a programmable divider (1, 2, 4 or 8) to
-give the readings more range or accuracy. Not all RPM values can
-accurately be represented, so some rounding is done. With a divider
-of 2, the lowest representable value is around 1900 RPM.
-
-Voltage sensors (also known as VIN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum or
-maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. The VDD input
-measures voltages between 0.000 and 5.865 volt, with a resolution of 0.023
-volt. The other inputs measure voltages between 0.000 and 4.845 volt, with
-a resolution of 0.019 volt. Note that revision 0x00 chips do not support
-reading the current voltage of any input except for VIN3; limit setting and
-alarms work fine, though.
-
-When an alarm is triggered, you can be warned by a beeping signal through your
-computer speaker. It is possible to enable all beeping globally, or only the
-beeping for some alarms.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once (except for temperature alarms). This means that the
-cause for the alarm may already have disappeared! Note that in the current
-implementation, all hardware registers are read whenever any data is read
-(unless it is less than 1.5 seconds since the last update). This means that
-you can easily miss once-only alarms.
-
-The GL518SM only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.

-Description
------------
-
-This driver implements support for the IT8705F, IT8712F and SiS950 chips.
-
-This driver also supports IT8712F, which adds SMBus access, and a VID
-input, used to report the Vcore voltage of the Pentium processor.
-The IT8712F additionally features VID inputs.
-
-These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
-joysticks and other miscellaneous stuff. For hardware monitoring, they
-include an 'environment controller' with 3 temperature sensors, 3 fan
-rotation speed sensors, 8 voltage sensors, and associated alarms.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the Overtemperature Shutdown limit is crossed.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give the
-readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts. An
-alarm is triggered if the voltage has crossed a programmable minimum or
-maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 4.08 volts, with a resolution of
-0.016 volt. The battery voltage in8 does not have limit registers.
-
-The VID lines (IT8712F only) encode the core voltage value: the voltage
-level your processor should work with. This is hardcoded by the mainboard
-and/or processor itself. It is a value in volts.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that in the current implementation, all hardware
-registers are read whenever any data is read (unless it is less than 1.5

-once-only alarms.
-
-The IT87xx only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.
-
-To change sensor N to a thermistor, 'echo 2 > tempN_type' where N is 1, 2,
-or 3. To change sensor N to a thermal diode, 'echo 3 > tempN_type'.
-Give 0 for unused sensor. Any other value is invalid. To configure this at
-startup, consult lm_sensors's /etc/sensors.conf. (2 = thermistor;
-3 = thermal diode)
-
-The fan speed control features are limited to manual PWM mode. Automatic

-Kernel driver lm63
-==================
-
-Supported chips:
- * National Semiconductor LM63
- Prefix: 'lm63'
- Addresses scanned: I2C 0x4c
- Datasheet: Publicly available at the National Semiconductor website
- http://www.national.com/pf/LM/LM63.html
-
-Author: Jean Delvare <khali@linux-fr.org>
-
-Thanks go to Tyan and especially Alex Buckingham for setting up a remote
-access to their S4882 test platform for this driver.
- http://www.tyan.com/
-
-Description
------------
-
-The LM63 is a digital temperature sensor with integrated fan monitoring
-and control.
-
-The LM63 is basically an LM86 with fan speed monitoring and control
-capabilities added. It misses some of the LM86 features though:
- - No low limit for local temperature.
- - No critical limit for local temperature.
- - Critical limit for remote temperature can be changed only once. We
- will consider that the critical limit is read-only.
-
-The datasheet isn't very clear about what the tachometer reading is.
-
-An explanation from National Semiconductor: The two lower bits of the read
-value have to be masked out. The value is still 16 bit in width.
-
-All temperature values are given in degrees Celsius. Resolution is 1.0
-degree for the local temperature, 0.125 degree for the remote temperature.
-
-The fan speed is measured using a tachometer. Contrary to most chips which
-store the value in an 8-bit register and have a selectable clock divider
-to make sure that the result will fit in the register, the LM63 uses 16-bit
-value for measuring the speed of the fan. It can measure fan speeds down to
-83 RPM, at least in theory.
-
-Note that the pin used for fan monitoring is shared with an alert out
-function. Depending on how the board designer wanted to use the chip, fan
-speed monitoring will or will not be possible. The proper chip configuration
-is left to the BIOS, and the driver will blindly trust it.
-
-A PWM output can be used to control the speed of the fan. The LM63 has two
-PWM modes: manual and automatic. Automatic mode is not fully implemented yet
-(you cannot define your custom PWM/temperature curve), and mode change isn't
-supported either.
-
-The lm63 driver will not update its values more frequently than every
-second; reading them more often will do no harm, but will return 'old'
-values.

-Description
------------
-
-The LM75 implements one temperature sensor. Limits can be set through the
-Overtemperature Shutdown register and Hysteresis register. Each value can be
-set and read to half-degree accuracy.
-An alarm is issued (usually to a connected LM78) when the temperature
-gets higher then the Overtemperature Shutdown value; it stays on until
-the temperature falls below the Hysteresis value.
-All temperatures are in degrees Celsius, and are guaranteed within a
-range of -55 to +125 degrees.
-
-The LM75 only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.
-
-The LM75 is usually used in combination with LM78-like chips, to measure
-the temperature of the processor(s).
-
-The DS75, DS1775, MAX6625, and MAX6626 are supported as well.
-They are not distinguished from an LM75. While most of these chips
-have three additional bits of accuracy (12 vs. 9 for the LM75),
-the additional bits are not supported. Not only that, but these chips will
-not be detected if not in 9-bit precision mode (use the force parameter if
-needed).
-
-The TCN75 is supported as well, and is not distinguished from an LM75.
-
-The LM75 is essentially an industry standard; there may be other
-LM75 clones not listed here, with or without various enhancements,
-that are supported.
-
-The LM77 is not supported, contrary to what we pretended for a long time.
-Both chips are simply not compatible, value encoding differs.

-Description
------------
-
-This driver implements support for the National Semiconductor LM78, LM78-J
-and LM79. They are described as 'Microprocessor System Hardware Monitors'.
-
-There is almost no difference between the three supported chips. Functionally,
-the LM78 and LM78-J are exactly identical. The LM79 has one more VID line,
-which is used to report the lower voltages newer Pentium processors use.
-From here on, LM7* means either of these three types.
-
-The LM7* implements one temperature sensor, three fan rotation speed sensors,
-seven voltage sensors, VID lines, alarms, and some miscellaneous stuff.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the Overtemperature Shutdown limit is crossed; it is triggered again
-as soon as it drops below the Hysteresis value. A more useful behavior
-can be found by setting the Hysteresis value to +127 degrees Celsius; in
-this case, alarms are issued during all the time when the actual temperature
-is above the Overtemperature Shutdown value. Measurements are guaranteed
-between -55 and +125 degrees, with a resolution of 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 4.08 volts, with a resolution
-of 0.016 volt.
-
-The VID lines encode the core voltage value: the voltage level your processor
-should work with. This is hardcoded by the mainboard and/or processor itself.
-It is a value in volts. When it is unconnected, you will often find the
-value 3.50 V here.
-
-In addition to the alarms described above, there are a couple of additional
-ones. There is a BTI alarm, which gets triggered when an external chip has
-crossed its limits. Usually, this is connected to all LM75 chips; if at
-least one crosses its limits, this bit gets set. The CHAS alarm triggers
-if your computer case is open. The FIFO alarms should never trigger; it
-indicates an internal error. The SMI_IN alarm indicates some other chip
-has triggered an SMI interrupt. As we do not use SMI interrupts at all,
-this condition usually indicates there is a problem with some other
-device.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The LM7* only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.

-
-The LM80 implements one temperature sensor, two fan rotation speed sensors,
-seven voltage sensors, alarms, and some miscellaneous stuff.
-
-Temperatures are measured in degrees Celsius. There are two sets of limits
-which operate independently. When the HOT Temperature Limit is crossed,
-this will cause an alarm that will be reasserted until the temperature
-drops below the HOT Hysteresis. The Overtemperature Shutdown (OS) limits
-should work in the same way (but this must be checked; the datasheet
-is unclear about this). Measurements are guaranteed between -55 and

-Kernel driver lm83
-==================
-
-Supported chips:
- * National Semiconductor LM83
- Prefix: 'lm83'
- Addresses scanned: I2C 0x18 - 0x1a, 0x29 - 0x2b, 0x4c - 0x4e
- Datasheet: Publicly available at the National Semiconductor website
- http://www.national.com/pf/LM/LM83.html
-
-
-Author: Jean Delvare <khali@linux-fr.org>
-
-Description
------------
-
-The LM83 is a digital temperature sensor. It senses its own temperature as
-well as the temperature of up to three external diodes. It is compatible
-with many other devices such as the LM84 and all other ADM1021 clones.
-The main difference between the LM83 and the LM84 in that the later can
-only sense the temperature of one external diode.
-
-Using the adm1021 driver for a LM83 should work, but only two temperatures
-will be reported instead of four.
-
-The LM83 is only found on a handful of motherboards. Both a confirmed
-list and an unconfirmed list follow. If you can confirm or infirm the
-fact that any of these motherboards do actually have an LM83, please
-contact us. Note that the LM90 can easily be misdetected as a LM83.
-
-Confirmed motherboards:
- SBS P014
-
-Unconfirmed motherboards:
- Gigabyte GA-8IK1100
- Iwill MPX2
- Soltek SL-75DRV5
-
-The driver has been successfully tested by Magnus Forsström, who I'd
-like to thank here. More testers will be of course welcome.
-
-The fact that the LM83 is only scarcely used can be easily explained.
-Most motherboards come with more than just temperature sensors for
-health monitoring. They also have voltage and fan rotation speed
-sensors. This means that temperature-only chips are usually used as
-secondary chips coupled with another chip such as an IT8705F or similar
-chip, which provides more features. Since systems usually need three
-temperature sensors (motherboard, processor, power supply) and primary
-chips provide some temperature sensors, the secondary chip, if needed,
-won't have to handle more than two temperatures. Thus, ADM1021 clones
-are sufficient, and there is no need for a four temperatures sensor
-chip such as the LM83. The only case where using an LM83 would make
-sense is on SMP systems, such as the above-mentioned Iwill MPX2,
-because you want an additional temperature sensor for each additional
-CPU.
-
-On the SBS P014, this is different, since the LM83 is the only hardware
-monitoring chipset. One temperature sensor is used for the motherboard
-(actually measuring the LM83's own temperature), one is used for the
-CPU. The two other sensors must be used to measure the temperature of
-two other points of the motherboard. We suspect these points to be the
-north and south bridges, but this couldn't be confirmed.
-
-All temperature values are given in degrees Celsius. Local temperature
-is given within a range of 0 to +85 degrees. Remote temperatures are
-given within a range of 0 to +125 degrees. Resolution is 1.0 degree,
-accuracy is guaranteed to 3.0 degrees (see the datasheet for more
-details).
-
-Each sensor has its own high limit, but the critical limit is common to
-all four sensors. There is no hysteresis mechanism as found on most
-recent temperature sensors.
-
-The lm83 driver will not update its values more frequently than every
-other second; reading them more often will do no harm, but will return
-'old' values.

-Description
------------
-
-This driver implements support for the National Semiconductor LM85 and
-compatible chips including the Analog Devices ADM1027, ADT7463 and
-SMSC EMC6D10x chips family.
-
-The LM85 uses the 2-wire interface compatible with the SMBUS 2.0
-specification. Using an analog to digital converter it measures three (3)
-temperatures and five (5) voltages. It has four (4) 16-bit counters for
-measuring fan speed. Five (5) digital inputs are provided for sampling the
-VID signals from the processor to the VRM. Lastly, there are three (3) PWM
-outputs that can be used to control fan speed.
-
-The voltage inputs have internal scaling resistors so that the following
-voltage can be measured without external resistors:
-
- 2.5V, 3.3V, 5V, 12V, and CPU core voltage (2.25V)
-
-The temperatures measured are one internal diode, and two remote diodes.
-Remote 1 is generally the CPU temperature. These inputs are designed to
-measure a thermal diode like the one in a Pentium 4 processor in a socket
-423 or socket 478 package. They can also measure temperature using a
-transistor like the 2N3904.
-
-A sophisticated control system for the PWM outputs is designed into the
-LM85 that allows fan speed to be adjusted automatically based on any of the
-three temperature sensors. Each PWM output is individually adjustable and
-programmable. Once configured, the LM85 will adjust the PWM outputs in
-response to the measured temperatures without further host intervention.
-This feature can also be disabled for manual control of the PWM's.
-
-Each of the measured inputs (voltage, temperature, fan speed) has
-corresponding high/low limit values. The LM85 will signal an ALARM if any
-measured value exceeds either limit.
-
-The LM85 samples all inputs continuously. The lm85 driver will not read
-the registers more often than once a second. Further, configuration data is
-only read once each 5 minutes. There is twice as much config data as
-measurements, so this would seem to be a worthwhile optimization.
-
-Special Features
-----------------
-
-The LM85 has four fan speed monitoring modes. The ADM1027 has only two.
-Both have special circuitry to compensate for PWM interactions with the
-TACH signal from the fans. The ADM1027 can be configured to measure the
-speed of a two wire fan, but the input conditioning circuitry is different
-for 3-wire and 2-wire mode. For this reason, the 2-wire fan modes are not
-exposed to user control. The BIOS should initialize them to the correct
-mode. If you've designed your own ADM1027, you'll have to modify the
-init_client function and add an insmod parameter to set this up.
-
-To smooth the response of fans to changes in temperature, the LM85 has an
-optional filter for smoothing temperatures. The ADM1027 has the same
-config option but uses it to rate limit the changes to fan speed instead.
-
-The ADM1027 and ADT7463 have a 10-bit ADC and can therefore measure
-temperatures with 0.25 degC resolution. They also provide an offset to the
-temperature readings that is automatically applied during measurement.
-This offset can be used to zero out any errors due to traces and placement.
-The documentation says that the offset is in 0.25 degC steps, but in
-initial testing of the ADM1027 it was 1.00 degC steps. Analog Devices has
-confirmed this "bug". The ADT7463 is reported to work as described in the
-documentation. The current lm85 driver does not show the offset register.
-
-The ADT7463 has a THERM asserted counter. This counter has a 22.76ms
-resolution and a range of 5.8 seconds. The driver implements a 32-bit
-accumulator of the counter value to extend the range to over a year. The
-counter will stay at it's max value until read.
-
-See the vendor datasheets for more information. There is application note
-from National (AN-1260) with some additional information about the LM85.
-The Analog Devices datasheet is very detailed and describes a procedure for
-determining an optimal configuration for the automatic PWM control.
-
-The SMSC EMC6D100 & EMC6D101 monitor external voltages, temperatures, and
-fan speeds. They use this monitoring capability to alert the system to out
-of limit conditions and can automatically control the speeds of multiple
-fans in a PC or embedded system. The EMC6D101, available in a 24-pin SSOP
-package, and the EMC6D100, available in a 28-pin SSOP package, are designed
-to be register compatible. The EMC6D100 offers all the features of the
-EMC6D101 plus additional voltage monitoring and system control features.
-Unfortunately it is not possible to distinguish between the package
-versions on register level so these additional voltage inputs may read
-zero. The EMC6D102 features addtional ADC bits thus extending precision
-of voltage and temperature channels.
-
-
-Hardware Configurations
------------------------
-
-The LM85 can be jumpered for 3 different SMBus addresses. There are
-no other hardware configuration options for the LM85.
-
-The lm85 driver detects both LM85B and LM85C revisions of the chip. See the
-datasheet for a complete description of the differences. Other than
-identifying the chip, the driver behaves no differently with regard to
-these two chips. The LM85B is recommended for new designs.
-
-The ADM1027 and ADT7463 chips have an optional SMBALERT output that can be
-used to signal the chipset in case a limit is exceeded or the temperature
-sensors fail. Individual sensor interrupts can be masked so they won't
-trigger SMBALERT. The SMBALERT output if configured replaces one of the other
-functions (PWM2 or IN0). This functionality is not implemented in current
-driver.
-
-The ADT7463 also has an optional THERM output/input which can be connected
-to the processor PROC_HOT output. If available, the autofan control
-dynamic Tmin feature can be enabled to keep the system temperature within
-spec (just?!) with the least possible fan noise.
-
-Configuration Notes
--------------------
-
-Besides standard interfaces driver adds following:
-
-* Temperatures and Zones
-
-Each temperature sensor is associated with a Zone. There are three
-sensors and therefore three zones (# 1, 2 and 3). Each zone has the following
-temperature configuration points:
-
-* temp#_auto_temp_off - temperature below which fans should be off or spinning very low.
-* temp#_auto_temp_min - temperature over which fans start to spin.
-* temp#_auto_temp_max - temperature when fans spin at full speed.
-* temp#_auto_temp_crit - temperature when all fans will run full speed.
-
-* PWM Control
-
-There are three PWM outputs. The LM85 datasheet suggests that the
-pwm3 output control both fan3 and fan4. Each PWM can be individually
-configured and assigned to a zone for it's control value. Each PWM can be
-configured individually according to the following options.
-
-* pwm#_auto_pwm_min - this specifies the PWM value for temp#_auto_temp_off
- temperature. (PWM value from 0 to 255)
-
-* pwm#_auto_pwm_freq - select base frequency of PWM output. You can select
- in range of 10.0 to 94.0 Hz in .1 Hz units.
- (Values 100 to 940).
-
-The pwm#_auto_pwm_freq can be set to one of the following 8 values. Setting the
-frequency to a value not on this list, will result in the next higher frequency
-being selected. The actual device frequency may vary slightly from this
-specification as designed by the manufacturer. Consult the datasheet for more
-details. (PWM Frequency values: 100, 150, 230, 300, 380, 470, 620, 940)
-
-* pwm#_auto_pwm_minctl - this flags selects for temp#_auto_temp_off temperature
- the bahaviour of fans. Write 1 to let fans spinning at
- pwm#_auto_pwm_min or write 0 to let them off.
-
-NOTE: It has been reported that there is a bug in the LM85 that causes the flag
-to be associated with the zones not the PWMs. This contradicts all the
-published documentation. Setting pwm#_min_ctl in this case actually affects all
-PWMs controlled by zone '#'.
-
-* PWM Controlling Zone selection
-
-* pwm#_auto_channels - controls zone that is associated with PWM
-
-Configuration choices:
-
- Value Meaning
- ------ ------------------------------------------------
- 1 Controlled by Zone 1
- 2 Controlled by Zone 2
- 3 Controlled by Zone 3
- 23 Controlled by higher temp of Zone 2 or 3
- 123 Controlled by highest temp of Zone 1, 2 or 3
- 0 PWM always 0% (off)
- -1 PWM always 100% (full on)
- -2 Manual control (write to 'pwm#' to set)
-
-The National LM85's have two vendor specific configuration
-features. Tach. mode and Spinup Control. For more details on these,
-see the LM85 datasheet or Application Note AN-1260.
-
-The Analog Devices ADM1027 has several vendor specific enhancements.
-The number of pulses-per-rev of the fans can be set, Tach monitoring
-can be optimized for PWM operation, and an offset can be applied to
-the temperatures to compensate for systemic errors in the
-measurements.
-
-In addition to the ADM1027 features, the ADT7463 also has Tmin control
-and THERM asserted counts. Automatic Tmin control acts to adjust the
-Tmin value to maintain the measured temperature sensor at a specified
-temperature. There isn't much documentation on this feature in the
-ADT7463 data sheet. This is not supported by current driver.

-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in
-volts. An alarm is triggered if the voltage has crossed a programmable
-minimum or maximum limit. Note that minimum in this case always means
-'closest to zero'; this is important for negative voltage measurements.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.0 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The lm87 driver only updates its values each 1.0 seconds; reading it more
-often will do no harm, but will return 'old' values.
-
-
-Hardware Configurations
------------------------
-
-The LM87 has four pins which can serve one of two possible functions,
-depending on the hardware configuration.
-
-Some functions share pins, so not all functions are available at the same
-time. Which are depends on the hardware setup. This driver assumes that
-the BIOS configured the chip correctly. In that respect, it differs from
-the original driver (from lm_sensors for Linux 2.4), which would force the
-LM87 to an arbitrary, compile-time chosen mode, regardless of the actual
-chipset wiring.
-
-For reference, here is the list of exclusive functions:
- - in0+in5 (default) or temp3
- - fan1 (default) or in6
- - fan2 (default) or in7
- - VID lines (default) or IRQ lines (not handled by this driver)

-Description
------------
-
-The LM90 is a digital temperature sensor. It senses its own temperature as
-well as the temperature of up to one external diode. It is compatible
-with many other devices such as the LM86, the LM89, the LM99, the ADM1032,
-the MAX6657, MAX6658 and the MAX6659 all of which are supported by this driver.
-Note that there is no easy way to differentiate between the last three
-variants. The extra address and features of the MAX6659 are not supported by
-this driver. Additionally, the ADT7461 is supported if found in ADM1032
-compatibility mode.
-
-The specificity of this family of chipsets over the ADM1021/LM84
-family is that it features critical limits with hysteresis, and an
-increased resolution of the remote temperature measurement.
-
-The different chipsets of the family are not strictly identical, although
-very similar. This driver doesn't handle any specific feature for now,
-but could if there ever was a need for it. For reference, here comes a
-non-exhaustive list of specific features:
-
-LM90:
- * Filter and alert configuration register at 0xBF.
- * ALERT is triggered by temperatures over critical limits.
-
-LM86 and LM89:
- * Same as LM90
- * Better external channel accuracy
-
-LM99:
- * Same as LM89
- * External temperature shifted by 16 degrees down
-
-ADM1032:
- * Consecutive alert register at 0x22.
- * Conversion averaging.
- * Up to 64 conversions/s.
- * ALERT is triggered by open remote sensor.
-
-ADT7461
- * Extended temperature range (breaks compatibility)
- * Lower resolution for remote temperature
-
-MAX6657 and MAX6658:
- * Remote sensor type selection
-
-MAX6659
- * Selectable address
- * Second critical temperature limit
- * Remote sensor type selection
-
-All temperature values are given in degrees Celsius. Resolution
-is 1.0 degree for the local temperature, 0.125 degree for the remote
-temperature.
-
-Each sensor has its own high and low limits, plus a critical limit.
-Additionally, there is a relative hysteresis value common to both critical
-values. To make life easier to user-space applications, two absolute values
-are exported, one for each channel, but these values are of course linked.
-Only the local hysteresis can be set from user-space, and the same delta
-applies to the remote hysteresis.
-
-The lm90 driver will not update its values more frequently than every
-other second; reading them more often will do no harm, but will return
-'old' values.

- Chip initialization level:
- 0: None
- *1: Forcibly enable internal voltage and temperature channels, except in9
- 2: Forcibly enable all voltage and temperature channels, except in9

-
-Also note that for the PC87366, initialization levels 2 and 3 don't enable
-all temperature channels, because some of them share pins with each other,

-
-
-Description
------------
-
-The National Semiconductor PC87360 Super I/O chip contains monitoring and
-PWM control circuitry for two fans. The PC87363 chip is similar, and the
-PC87364 chip has monitoring and PWM control for a third fan.
-
-The National Semiconductor PC87365 and PC87366 Super I/O chips are complete
-hardware monitoring chipsets, not only controlling and monitoring three fans,
-but also monitoring eleven voltage inputs and two (PC87365) or up to four
-(PC87366) temperatures.
-
- Chip #vin #fan #pwm #temp devid

- PC87360 - 2 2 - 0xE1
- PC87363 - 2 2 - 0xE8
- PC87364 - 3 3 - 0xE4
- PC87365 11 3 3 2 0xE5
- PC87366 11 3 3 3-4 0xE9
-
-The driver assumes that no more than one chip is present, and one of the
-standard Super I/O addresses is used (0x2E/0x2F or 0x4E/0x4F)
-
-Fan Monitoring
---------------
-
-Fan rotation speeds are reported in RPM (revolutions per minute). An alarm
-is triggered if the rotation speed has dropped below a programmable limit.
-A different alarm is triggered if the fan speed is too low to be measured.
-
-Fan readings are affected by a programmable clock divider, giving the
-readings more range or accuracy. Usually, users have to learn how it works,
-but this driver implements dynamic clock divider selection, so you don't
-have to care no more.
-
-For reference, here are a few values about clock dividers:
-
- slowest accuracy highest
- measurable around 3000 accurate
- divider speed (RPM) RPM (RPM) speed (RPM)
- 1 1882 18 6928
- 2 941 37 4898
- 4 470 74 3464
- 8 235 150 2449
-
-For the curious, here is how the values above were computed:
- * slowest measurable speed: clock/(255*divider)
- * accuracy around 3000 RPM: 3000^2/clock
- * highest accurate speed: sqrt(clock*100)
-The clock speed for the PC87360 family is 480 kHz. I arbitrarily chose 100
-RPM as the lowest acceptable accuracy.
-
-As mentioned above, you don't have to care about this no more.
-
-Note that not all RPM values can be represented, even when the best clock
-divider is selected. This is not only true for the measured speeds, but
-also for the programmable low limits, so don't be surprised if you try to
-set, say, fan1_min to 2900 and it finally reads 2909.
-
-
-Fan Control
------------
-
-PWM (pulse width modulation) values range from 0 to 255, with 0 meaning
-that the fan is stopped, and 255 meaning that the fan goes at full speed.
-
-Be extremely careful when changing PWM values. Low PWM values, even
-non-zero, can stop the fan, which may cause irreversible damage to your
-hardware if temperature increases too much. When changing PWM values, go
-step by step and keep an eye on temperatures.
-
-One user reported problems with PWM. Changing PWM values would break fan
-speed readings. No explanation nor fix could be found.
-
-
-Temperature Monitoring
-----------------------
-
-Temperatures are reported in degrees Celsius. Each temperature measured has
-associated low, high and overtemperature limits, each of which triggers an
-alarm when crossed.
-
-The first two temperature channels are external. The third one (PC87366
-only) is internal.
-
-The PC87366 has three additional temperature channels, based on
-thermistors (as opposed to thermal diodes for the first three temperature
-channels). For technical reasons, these channels are held by the VLM
-(voltage level monitor) logical device, not the TMS (temperature
-measurement) one. As a consequence, these temperatures are exported as
-voltages, and converted into temperatures in user-space.
-
-Note that these three additional channels share their pins with the
-external thermal diode channels, so you (physically) can't use them all at
-the same time. Although it should be possible to mix the two sensor types,
-the documents from National Semiconductor suggest that motherboard
-manufacturers should choose one type and stick to it. So you will more
-likely have either channels 1 to 3 (thermal diodes) or 3 to 6 (internal
-thermal diode, and thermistors).
-
-
-Voltage Monitoring
-------------------
-
-Voltages are reported relatively to a reference voltage, either internal or
-external. Some of them (in7:Vsb, in8:Vdd and in10:AVdd) are divided by two
-internally, you will have to compensate in sensors.conf. Others (in0 to in6)
-are likely to be divided externally. The meaning of each of these inputs as
-well as the values of the resistors used for division is left to the
-motherboard manufacturers, so you will have to document yourself and edit
-sensors.conf accordingly. National Semiconductor has a document with
-recommended resistor values for some voltages, but this still leaves much
-room for per motherboard specificities, unfortunately. Even worse,
-motherboard manufacturers don't seem to care about National Semiconductor's
-recommendations.
-
-Each voltage measured has associated low and high limits, each of which
-triggers an alarm when crossed.
-
-When available, VID inputs are used to provide the nominal CPU Core voltage.
-The driver will default to VRM 9.0, but this can be changed from user-space.
-The chipsets can handle two sets of VID inputs (on dual-CPU systems), but
-the driver will only export one for now. This may change later if there is
-a need.
-
-
-General Remarks
----------------
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that all hardware registers are read whenever any
-data is read (unless it is less than 2 seconds since the last update, in
-which case cached values are returned instead). As a consequence, when
-a once-only alarm triggers, it may take 2 seconds for it to show, and 2
-more seconds for it to disappear.
-
-Monitoring of in9 isn't enabled at lower init levels (<3) because that
-channel measures the battery voltage (Vbat). It is a known fact that
-repeatedly sampling the battery voltage reduces its lifetime. National
-Semiconductor smartly designed their chipset so that in9 is sampled only
-once every 1024 sampling cycles (that is every 34 minutes at the default
-sampling rate), so the effect is attenuated, but still present.
-
-
-Limitations
------------
-
-The datasheets suggests that some values (fan mins, fan dividers)
-shouldn't be changed once the monitoring has started, but we ignore that
-recommendation. We'll reconsider if it actually causes trouble.

-
-Description
------------
-
-The SiS5595 southbridge has integrated hardware monitor functions. It also
-has an I2C bus, but this driver only supports the hardware monitor. For the
-I2C bus driver see i2c-sis5595.
-
-The SiS5595 implements zero or one temperature sensor, two fan speed
-sensors, four or five voltage sensors, and alarms.
-
-On the first version of the chip, there are four voltage sensors and one
-temperature sensor.
-
-On the second version of the chip, the temperature sensor (temp) and the
-fifth voltage sensor (in4) share a pin which is configurable, but not
-through the driver. Sorry. The driver senses the configuration of the pin,
-which was hopefully set by the BIOS.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the max is crossed; it is also triggered when it drops below the min
-value. Measurements are guaranteed between -55 and +125 degrees, with a
-resolution of 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts. An
-alarm is triggered if the voltage has crossed a programmable minimum or
-maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 4.08 volts, with a resolution of
-0.016 volt.
-
-In addition to the alarms described above, there is a BTI alarm, which gets
-triggered when an external chip has crossed its limits. Usually, this is
-connected to some LM75-like chip; if at least one crosses its limits, this
-bit gets set.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that in the current implementation, all hardware
-registers are read whenever any data is read (unless it is less than 1.5
-seconds since the last update). This means that you can easily miss
-once-only alarms.
-
-The SiS5595 only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.
-
-Problems
---------
-Some chips refuse to be enabled. We don't know why.
-The driver will recognize this and print a message in dmesg.

-Methods for detecting the HP SIO and reading the thermal data on a dc7100.
-
-The thermal information on the dc7100 is contained in the SIO Hardware Monitor
-(HWM). The information is accessed through an index/data pair. The index/data
-pair is located at the HWM Base Address + 0 and the HWM Base Address + 1. The
-HWM Base address can be obtained from Logical Device 8, registers 0x60 (MSB)
-and 0x61 (LSB). Currently we are using 0x480 for the HWM Base Address and
-0x480 and 0x481 for the index/data pair.
-
-Reading temperature information.
-The temperature information is located in the following registers:
-Temp1 0x25 (Currently, this reflects the CPU temp on all systems).
-Temp2 0x26
-Temp3 0x27
-Temp4 0x80
-
-Programming Example
-The following is an example of how to read the HWM temperature registers:
-MOV DX,480H
-MOV AX,25H
-OUT DX,AL
-MOV DX,481H
-IN AL,DX
-
-AL contains the data in hex, the temperature in Celsius is the decimal
-equivalent.
-
-Ex: If AL contains 0x2A, the temperature is 42 degrees C.
-
-Reading tach information.
-The fan speed information is located in the following registers:
- LSB MSB
-Tach1 0x28 0x29 (Currently, this reflects the CPU
- fan speed on all systems).
-Tach2 0x2A 0x2B
-Tach3 0x2C 0x2D
-Tach4 0x2E 0x2F
-
-Important!!!
-Reading the tach LSB locks the tach MSB.
-The LSB Must be read first.
-
-How to convert the tach reading to RPM.
-The tach reading (TCount) is given by: (Tach MSB * 256) + (Tach LSB)
-The SIO counts the number of 90kHz (11.111us) pulses per revolution.
-RPM = 60/(TCount * 11.111us)
-
-Example:
-Reg 0x28 = 0x9B
-Reg 0x29 = 0x08
-

-RPM = 60 / (2203 * 11.11111 E-6) = 2451 RPM
-
-Obtaining the SIO version.
-
-CONFIGURATION SEQUENCE
-To program the configuration registers, the following sequence must be followed:
-1. Enter Configuration Mode
-2. Configure the Configuration Registers
-3. Exit Configuration Mode.
-
-Enter Configuration Mode
-To place the chip into the Configuration State The config key (0x55) is written
-to the CONFIG PORT (0x2E).
-
-Configuration Mode
-In configuration mode, the INDEX PORT is located at the CONFIG PORT address and
-the DATA PORT is at INDEX PORT address + 1.
-
-The desired configuration registers are accessed in two steps:
-a. Write the index of the Logical Device Number Configuration Register
- (i.e., 0x07) to the INDEX PORT and then write the number of the
- desired logical device to the DATA PORT.
-
-b. Write the address of the desired configuration register within the
- logical device to the INDEX PORT and then write or read the config-
- uration register through the DATA PORT.
-
-Note: If accessing the Global Configuration Registers, step (a) is not required.
-
-Exit Configuration Mode
-To exit the Configuration State the write 0xAA to the CONFIG PORT (0x2E).
-The chip returns to the RUN State. (This is important).
-
-Programming Example
-The following is an example of how to read the SIO Device ID located at 0x20
-
-; ENTER CONFIGURATION MODE
-MOV DX,02EH
-MOV AX,055H
-OUT DX,AL
-; GLOBAL CONFIGURATION REGISTER
-MOV DX,02EH
-MOV AL,20H
-OUT DX,AL
-; READ THE DATA
-MOV DX,02FH
-IN AL,DX
-; EXIT CONFIGURATION MODE
-MOV DX,02EH
-MOV AX,0AAH
-OUT DX,AL
-
-The registers of interest for identifying the SIO on the dc7100 are Device ID
-(0x20) and Device Rev (0x21).
-
-The Device ID will read 0X6F
-The Device Rev currently reads 0x01
-
-Obtaining the HWM Base Address.
-The following is an example of how to read the HWM Base Address located in
-Logical Device 8.
-
-; ENTER CONFIGURATION MODE
-MOV DX,02EH
-MOV AX,055H
-OUT DX,AL
-; CONFIGURE REGISTER CRE0,
-; LOGICAL DEVICE 8
-MOV DX,02EH
-MOV AL,07H
-OUT DX,AL ;Point to LD# Config Reg
-MOV DX,02FH
-MOV AL, 08H
-OUT DX,AL;Point to Logical Device 8
-;
-MOV DX,02EH
-MOV AL,60H
-OUT DX,AL ; Point to HWM Base Addr MSB
-MOV DX,02FH
-IN AL,DX ; Get MSB of HWM Base Addr
-; EXIT CONFIGURATION MODE
-MOV DX,02EH

-Description
------------
-
-The Standard Microsystems Corporation (SMSC) 47M1xx Super I/O chips
-contain monitoring and PWM control circuitry for two fans.
-
-The 47M15x and 47M192 chips contain a full 'hardware monitoring block'
-in addition to the fan monitoring and control. The hardware monitoring
-block is not supported by the driver.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-PWM values are from 0 to 255.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.

-Kernel driver via686a

-
-Module Parameters
------------------
-
-force_addr=0xaddr Set the I/O base address. Useful for Asus A7V boards
- that don't set the address in the BIOS. Does not do a
- PCI force; the via686a must still be present in lspci.
- Don't use this unless the driver complains that the
- base address is not set.
- Example: 'modprobe via686a force_addr=0x6000'
-
-Description
------------
-
-The driver does not distinguish between the chips and reports
-all as a 686A.
-
-The Via 686a southbridge has integrated hardware monitor functionality.
-It also has an I2C bus, but this driver only supports the hardware monitor.
-For the I2C bus driver, see <file:Documentation/i2c/busses/i2c-viapro>
-
-The Via 686a implements three temperature sensors, two fan rotation speed
-sensors, five voltage sensors and alarms.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the Overtemperature Shutdown limit is crossed; it is triggered again
-as soon as it drops below the hysteresis value.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Voltages are internally scalled, so each voltage channel
-has a different resolution and range.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The driver only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.

------------------
-
-* force_addr: int
- Initialize the ISA address of the sensors
-* force_i2c: int
- Initialize the I2C address of the sensors
-* init: int
- (default is 1)

- Try this if your computer crashes when you load the module.
-
-Description
------------
-
-This driver implements support for ISA accesses *only* for
-the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
-We will refer to them collectively as Winbond chips.
-
-This driver supports ISA accesses, which should be more reliable
-than i2c accesses. Also, for Tyan boards which contain both a
-Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
-using this driver will avoid i2c address conflicts and complex
-initialization that were required in the w83781d driver.
-
-If you really want i2c accesses for these Super I/O chips,
-use the w83781d driver. However this is not the preferred method
-now that this ISA driver has been developed.
-
-Technically, the w83627thf does not support a VID reading. However, it's
-possible or even likely that your mainboard maker has routed these signals
-to a specific set of general purpose IO pins (the Asus P4C800-E is one such
-board). The w83627thf driver now interprets these as VID. If the VID on
-your board doesn't work, first see doc/vid in the lm_sensors package. If
-that still doesn't help, email us at lm-sensors@lm-sensors.org.
-
-For further information on this driver see the w83781d driver
-documentation.

-Description
------------
-
-This driver implements support for the Winbond W83781D, W83782D, W83783S,
-W83627HF chips, and the Asus AS99127F chips. We will refer to them
-collectively as W8378* chips.
-
-There is quite some difference between these chips, but they are similar
-enough that it was sensible to put them together in one driver.
-The W83627HF chip is assumed to be identical to the ISA W83782D.
-The Asus chips are similar to an I2C-only W83782D.

-w83783s 5-6 3 2 1-2 0x40 0x5ca3 yes no
-
-Detection of these chips can sometimes be foiled because they can be in
-an internal state that allows no clean access. If you know the address
-of the chip, use a 'force' parameter; this will put them into a more
-well-behaved state first.
-
-The W8378* implements temperature sensors (three on the W83781D and W83782D,
-two on the W83783S), three fan rotation speed sensors, voltage sensors
-(seven on the W83781D, nine on the W83782D and six on the W83783S), VID
-lines, alarms with beep warnings, and some miscellaneous stuff.
-
-Temperatures are measured in degrees Celsius. There is always one main
-temperature sensor, and one (W83783S) or two (W83781D and W83782D) other
-sensors. An alarm is triggered for the main sensor once when the
-Overtemperature Shutdown limit is crossed; it is triggered again as soon as
-it drops below the Hysteresis value. A more useful behavior
-can be found by setting the Hysteresis value to +127 degrees Celsius; in
-this case, alarms are issued during all the time when the actual temperature
-is above the Overtemperature Shutdown value. The driver sets the
-hysteresis value for temp1 to 127 at initialization.
-
-For the other temperature sensor(s), an alarm is triggered when the
-temperature gets higher then the Overtemperature Shutdown value; it stays
-on until the temperature falls below the Hysteresis value. But on the
-W83781D, there is only one alarm that functions for both other sensors!
-Temperatures are guaranteed within a range of -55 to +125 degrees. The
-main temperature sensors has a resolution of 1 degree; the other sensor(s)
-of 0.5 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8 for the
-W83781D; 1, 2, 4, 8, 16, 32, 64 or 128 for the others) to give
-the readings more range or accuracy. Not all RPM values can accurately
-be represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 4.08 volts, with a resolution
-of 0.016 volt.
-
-The VID lines encode the core voltage value: the voltage level your processor
-should work with. This is hardcoded by the mainboard and/or processor itself.
-It is a value in volts. When it is unconnected, you will often find the
-value 3.50 V here.
-
-The W83782D and W83783S temperature conversion machine understands about
-several kinds of temperature probes. You can program the so-called
-beta value in the sensor files. '1' is the PII/Celeron diode, '2' is the
-TN3904 transistor, and 3435 the default thermistor value. Other values
-are (not yet) supported.
-
-In addition to the alarms described above, there is a CHAS alarm on the
-chips which triggers if your computer case is open.
-
-When an alarm goes off, you can be warned by a beeping signal through
-your computer speaker. It is possible to enable all beeping globally,
-or only the beeping for some alarms.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The chips only update values each 1.5 seconds; reading them more often
-will do no harm, but will return 'old' values.
-
-AS99127F PROBLEMS
------------------
-The as99127f support was developed without the benefit of a datasheet.
-In most cases it is treated as a w83781d (although revision 2 of the
-AS99127F looks more like a w83782d).
-This support will be BETA until a datasheet is released.
-One user has reported problems with fans stopping
-occasionally.
-
-Note that the individual beep bits are inverted from the other chips.
-The driver now takes care of this so that user-space applications
-don't have to know about it.
-
-Known problems:
- - Problems with diode/thermistor settings (supported?)
- - One user reports fans stopping under high server load.
- - Revision 2 seems to have 2 PWM registers but we don't know
- how to handle them. More details below.
-
-These will not be fixed unless we get a datasheet.
-If you have problems, please lobby Asus to release a datasheet.
-Unfortunately several others have without success.
-Please do not send mail to us asking for better as99127f support.
-We have done the best we can without a datasheet.
-Please do not send mail to the author or the sensors group asking for
-a datasheet or ideas on how to convince Asus. We can't help.
-
-
-NOTES:
------
- 783s has no in1 so that in[2-6] are compatible with the 781d/782d.
-
- 783s pin is programmable for -5V or temp1; defaults to -5V,
- no control in driver so temp1 doesn't work.
-
- 782d and 783s datasheets differ on which is pwm1 and which is pwm2.
- We chose to follow 782d.
-
- 782d and 783s pin is programmable for fan3 input or pwm2 output;
- defaults to fan3 input.
- If pwm2 is enabled (with echo 255 1 > pwm2), then
- fan3 will report 0.
-
- 782d has pwm1-2 for ISA, pwm1-4 for i2c. (pwm3-4 share pins with
- the ISA pins)
-
-Data sheet updates:

- 000: master / 512
- 001: master / 1024
- 010: master / 2048

-Answers from Winbond tech support
----------------------------------
->
-> 1) In the W83781D data sheet section 7.2 last paragraph, it talks about
-> reprogramming the R-T table if the Beta of the thermistor is not
-> 3435K. The R-T table is described briefly in section 8.20.
-> What formulas do I use to program a new R-T table for a given Beta?
->
- We are sorry that the calculation for R-T table value is
-confidential. If you have another Beta value of thermistor, we can help
-to calculate the R-T table for you. But you should give us real R-T
-Table which can be gotten by thermistor vendor. Therefore we will calculate
-them and obtain 32-byte data, and you can fill the 32-byte data to the
-register in Bank0.CR51 of W83781D.
-
-
-> 2) In the W83782D data sheet, it mentions that pins 38, 39, and 40 are
-> programmable to be either thermistor or Pentium II diode inputs.
-> How do I program them for diode inputs? I can't find any register
-> to program these to be diode inputs.
- --> You may program Bank0 CR[5Dh] and CR[59h] registers.

-Asus Clones
------------
-
-We have no datasheets for the Asus clones (AS99127F and ASB100 Bach).
-Here are some very useful information that were given to us by Alex Van
-Kaam about how to detect these chips, and how to read their values. He
-also gives advice for another Asus chipset, the Mozart-2 (which we
-don't support yet). Thanks Alex!
-I reworded some parts and added personal comments.
-
-# Detection:
-
-AS99127F rev.1, AS99127F rev.2 and ASB100:
-- I2C address range: 0x29 - 0x2F
-- If register 0x58 holds 0x31 then we have an Asus (either ASB100 or
- AS99127F)
-- Which one depends on register 0x4F (manufacturer ID):
- 0x06 or 0x94: ASB100
- 0x12 or 0xC3: AS99127F rev.1
- 0x5C or 0xA3: AS99127F rev.2
- Note that 0x5CA3 is Winbond's ID (WEC), which let us think Asus get their
- AS99127F rev.2 direct from Winbond. The other codes mean ATT and DVC,
- respectively. ATT could stand for Asustek something (although it would be
- very badly chosen IMHO), I don't know what DVC could stand for. Maybe
- these codes simply aren't meant to be decoded that way.
-
-Mozart-2:
-- I2C address: 0x77
-- If register 0x58 holds 0x56 or 0x10 then we have a Mozart-2
-- Of the Mozart there are 3 types:
- 0x58=0x56, 0x4E=0x94, 0x4F=0x36: Asus ASM58 Mozart-2
- 0x58=0x56, 0x4E=0x94, 0x4F=0x06: Asus AS2K129R Mozart-2
- 0x58=0x10, 0x4E=0x5C, 0x4F=0xA3: Asus ??? Mozart-2
- You can handle all 3 the exact same way :)
-
-# Temperature sensors:
-
-ASB100:
-- sensor 1: register 0x27
-- sensor 2 & 3 are the 2 LM75's on the SMBus
-- sensor 4: register 0x17
-Remark: I noticed that on Intel boards sensor 2 is used for the CPU
- and 4 is ignored/stuck, on AMD boards sensor 4 is the CPU and sensor 2 is
- either ignored or a socket temperature.
-
-AS99127F (rev.1 and 2 alike):
-- sensor 1: register 0x27
-- sensor 2 & 3 are the 2 LM75's on the SMBus
-Remark: Register 0x5b is suspected to be temperature type selector. Bit 1
- would control temp1, bit 3 temp2 and bit 5 temp3.
-
-Mozart-2:
-- sensor 1: register 0x27
-- sensor 2: register 0x13

-# PWM
-
-Additional info about PWM on the AS99127F (may apply to other Asus
-chips as well) by Jean Delvare as of 2004-04-09:
-
-AS99127F revision 2 seems to have two PWM registers at 0x59 and 0x5A,
-and a temperature sensor type selector at 0x5B (which basically means
-that they swapped registers 0x59 and 0x5B when you compare with Winbond
-chips).
-Revision 1 of the chip also has the temperature sensor type selector at
-0x5B, but PWM registers have no effect.
-
-We don't know exactly how the temperature sensor type selection works.
-Looks like bits 1-0 are for temp1, bits 3-2 for temp2 and bits 5-4 for
-temp3, although it is possible that only the most significant bit matters
-each time. So far, values other than 0 always broke the readings.
-
-PWM registers seem to be split in two parts: bit 7 is a mode selector,
-while the other bits seem to define a value or threshold.
-
-When bit 7 is clear, bits 6-0 seem to hold a threshold value. If the value
-is below a given limit, the fan runs at low speed. If the value is above
-the limit, the fan runs at full speed. We have no clue as to what the limit
-represents. Note that there seem to be some inertia in this mode, speed
-changes may need some time to trigger. Also, an hysteresis mechanism is
-suspected since walking through all the values increasingly and then
-decreasingly led to slightly different limits.
-
-When bit 7 is set, bits 3-0 seem to hold a threshold value, while bits 6-4
-would not be significant. If the value is below a given limit, the fan runs
-at full speed, while if it is above the limit it runs at low speed (so this
-is the contrary of the other mode, in a way). Here again, we don't know
-what the limit is supposed to represent.
-
-One remarkable thing is that the fans would only have two or three
-different speeds (transitional states left apart), not a whole range as
-you usually get with PWM.
-
-As a conclusion, you can write 0x00 or 0x8F to the PWM registers to make
-fans run at low speed, and 0x7F or 0x80 to make them run at full speed.
-
-Please contact us if you can figure out how it is supposed to work. As
-long as we don't know more, the w83781d driver doesn't handle PWM on
-AS99127F chips at all.
-
-Additional info about PWM on the AS99127F rev.1 by Hector Martin:
-
-I've been fiddling around with the (in)famous 0x59 register and
-found out the following values do work as a form of coarse pwm:
-
-0x80 - seems to turn fans off after some time(1-2 minutes)... might be
-some form of auto-fan-control based on temp? hmm (Qfan? this mobo is an
-old ASUS, it isn't marketed as Qfan. Maybe some beta pre-attemp at Qfan
-that was dropped at the BIOS)
-0x81 - off
-0x82 - slightly "on-ner" than off, but my fans do not get to move. I can
-hear the high-pitched PWM sound that motors give off at too-low-pwm.
-0x83 - now they do move. Estimate about 70% speed or so.
-0x84-0x8f - full on
-
-Changing the high nibble doesn't seem to do much except the high bit
-(0x80) must be set for PWM to work, else the current pwm doesn't seem to
-change.
-
-My mobo is an ASUS A7V266-E. This behavior is similar to what I got
-with speedfan under Windows, where 0-15% would be off, 15-2x% (can't
-remember the exact value) would be 70% and higher would be full on.

-Kernel driver w83l785ts
-=======================
-
-Supported chips:
- * Winbond W83L785TS-S
- Prefix: 'w83l785ts'
- Addresses scanned: I2C 0x2e
- Datasheet: Publicly available at the Winbond USA website
- http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83L785TS-S.pdf
-
-Authors:
- Jean Delvare <khali@linux-fr.org>

-Description
------------
-
-The W83L785TS-S is a digital temperature sensor. It senses the
-temperature of a single external diode. The high limit is
-theoretically defined as 85 or 100 degrees C through a combination
-of external resistors, so the user cannot change it. Values seen so
-far suggest that the two possible limits are actually 95 and 110
-degrees C. The datasheet is rather poor and obviously inaccurate
-on several points including this one.
-
-All temperature values are given in degrees Celsius. Resolution
-is 1.0 degree. See the datasheet for details.
-
-The w83l785ts driver will not update its values more frequently than
-every other second; reading them more often will do no harm, but will
-return 'old' values.
-
-Known Issues
-------------
-
-On some systems (Asus), the BIOS is known to interfere with the driver
-and cause read errors. The driver will retry a given number of times
-(5 by default) and then give up, returning the old value (or 0 if
-there is no old value). It seems to work well enough so that you should
-not notice anything. Thanks to James Bolt for helping test this feature.

-Naming and data format standards for sysfs files
-------------------------------------------------
-
-The libsensors library offers an interface to the raw sensors data
-through the sysfs interface. See libsensors documentation and source for
-more further information. As of writing this document, libsensors
-(from lm_sensors 2.8.3) is heavily chip-dependant. Adding or updating
-support for any given chip requires modifying the library's code.
-This is because libsensors was written for the procfs interface
-older kernel modules were using, which wasn't standardized enough.
-Recent versions of libsensors (from lm_sensors 2.8.2 and later) have
-support for the sysfs interface, though.
-
-The new sysfs interface was designed to be as chip-independant as
-possible.
-
-Note that motherboards vary widely in the connections to sensor chips.
-There is no standard that ensures, for example, that the second
-temperature sensor is connected to the CPU, or that the second fan is on
-the CPU. Also, some values reported by the chips need some computation
-before they make full sense. For example, most chips can only measure
-voltages between 0 and +4V. Other voltages are scaled back into that
-range using external resistors. Since the values of these resistors
-can change from motherboard to motherboard, the conversions cannot be
-hard coded into the driver and have to be done in user space.
-
-For this reason, even if we aim at a chip-independant libsensors, it will
-still require a configuration file (e.g. /etc/sensors.conf) for proper
-values conversion, labeling of inputs and hiding of unused inputs.
-
-An alternative method that some programs use is to access the sysfs
-files directly. This document briefly describes the standards that the
-drivers follow, so that an application program can scan for entries and
-access this data in a simple and consistent way. That said, such programs
-will have to implement conversion, labeling and hiding of inputs. For
-this reason, it is still not recommended to bypass the library.
-
-If you are developing a userspace application please send us feedback on
-this standard.
-
-Note that this standard isn't completely established yet, so it is subject
-to changes, even important ones. One more reason to use the library instead
-of accessing sysfs files directly.
-
-Each chip gets its own directory in the sysfs /sys/devices tree. To
-find all sensor chips, it is easier to follow the symlinks from
-/sys/i2c/devices/
-
-All sysfs values are fixed point numbers. To get the true value of some
-of the values, you should divide by the specified value.
-
-There is only one value per file, unlike the older /proc specification.
-The common scheme for files naming is: <type><number>_<item>. Usual
-types for sensor chips are "in" (voltage), "temp" (temperature) and
-"fan" (fan). Usual items are "input" (measured value), "max" (high
-threshold, "min" (low threshold). Numbering usually starts from 1,
-except for voltages which start from 0 (because most data sheets use
-this). A number is always used for elements that can be present more
-than once, even if there is a single element of the given type on the
-specific chip. Other files do not refer to a specific element, so
-they have a simple name, and no number.
-
-Alarms are direct indications read from the chips. The drivers do NOT
-make comparisons of readings to thresholds. This allows violations
-between readings to be caught and alarmed. The exact definition of an
-alarm (for example, whether a threshold must be met or must be exceeded
-to cause an alarm) is chip-dependent.

-Introduction
-------------
-
-Most mainboards have sensor chips to monitor system health (like temperatures,
-voltages, fans speed). They are often connected through an I2C bus, but some
-are also connected directly through the ISA bus.
-
-The kernel drivers make the data from the sensor chips available in the /sys
-virtual filesystem. Userspace tools are then used to display or set or the
-data in a more friendly manner.
-
-Lm-sensors
-----------
-
-Core set of utilites that will allow you to obtain health information,
-setup monitoring limits etc. You can get them on their homepage
-http://www.lm-sensors.nu/ or as a package from your Linux distribution.
-
-If from website:
-Get lmsensors from project web site. Please note, you need only userspace
-part, so compile with "make user_install" target.
-
-General hints to get things working:
-
-0) get lm-sensors userspace utils
-1) compile all drivers in I2C section as modules in your kernel
-2) run sensors-detect script, it will tell you what modules you need to load.
-3) load them and run "sensors" command, you should see some results.
-4) fix sensors.conf, labels, limits, fan divisors
-5) if any more problems consult FAQ, or documentation
-
-Other utilites
---------------
-
-If you want some graphical indicators of system health look for applications
-like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd,
-hardware-monitor
-
-If you are server administrator you can try snmpd or mrtgutils.
