2008-11-12adt7462: new hwmon driverDarrick J. Wong
New driver to play with. As Jean mentioned a couple of years ago, this chip is a beast with odd combinations of 8 fans, 4 temperatures, and 13 voltage sensors. This driver has been tested on an IntelliStation Z30. Signed-off-by: Darrick J.

2008-11-12LIS3LV02Dx Accelerometer driverPavel Machek
This adds a driver to the accelerometer sensor found in several HP laptops (under the commercial names of "HP Mobile Data Protection System 3D" and "HP 3D driveguard"). It tries to have more or less the same interfaces as the hdaps and other accelerometer drivers: in sysfs and as a joystick. This driver was first written by Yan Burman. Eric Piel has updated it and slimed it up (including the removal of an interface to access to the free-fall feature of the sensor because it is not reliable enough for now). Pavel Machek removed few more features and switched locking from semaphore to mutex. Several people have contributed to the database of the axes.

2008-10-26hwmon: (lm90) Add support for the LM99 16 degree offsetJean Delvare
The LM99 differs from the LM86, LM89 and LM90 in that it reports remote temperatures (temp2) 16 degrees lower than they really are. So far we have been cheating and handled this in userspace but it really should be handled by the driver directly.

2008-10-17hwmon: (w83781d) Additional information about AS99127F PWMJean Delvare
This information was provided in lm-sensors ticket #2350: http://www.lm-sensors.org/ticket/2350 This is IMHO still not enough to be able to safely implement fan control support for the AS99127F, but this is valuable information so I am adding it to the documentation.

2008-10-17hwmon: (it87) Fix thermal sensor type valuesJean Delvare
The it87 driver doesn't follow the standard sensor type values as documented in Documentation/hwmon/sysfs-interface. It uses value 2 for thermistors instead of value 4. This causes "sensors" to tell the user that the chip is setup for a transistor while it is actually setup for a thermistor. Using value 4 for thermistors solves the problem. For compatibility reasons, we still accept value 2 but emit a warning message so that users update their configuration files.

2008-10-17hwmon: (lm85) Implement the standard PWM frequency interfaceJean Delvare
Implement the standard PWM frequency interface: pwm[1-*]_freq in units of 1 Hz, instead of the non-standard pwm[1-*]_auto_pwm_freq in units of 0.1 Hz. The old naming was not only non-standard, it was also confusing, because it suggested that the frequency value only applied in automatic fan speed mode, which isn't true.

2008-10-17hwmon: (lm87) Add support for configuration through platform_dataBen Hutchings
The lm87 driver normally assumes that firmware configured the chip correctly. Since this is not always the case, alllow platform code to set the channel register value via platform_data. All other configuration registers can be changed after driver initialisation. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>

2008-10-17hwmon: (lm90) Update datasheet linksJean Delvare

2008-08-06hwmon: (w83627hf) Drop reset module parameterJean Delvare
Drop the reset parameter of the w83627hf driver. It seems it wasn't that useful. It was dropped from the Linux 2.4 version of this driver back in July 2004. The only users who have reported that they were still using this parameter, needed it to switch the chip from automatic fan speed control back to manual mode. Now that the driver creates pwmN_enable sysfs files, users will be able to use these files instead, which is way less agressive.

This patch adds support for the SMSC SCH3112, SCH3114, and SCH3116 Super-I/O chips. These chips feature identical hardware monitoring capabilites with the expection that some of the fan inputs and pmw outputs don't exist. The hardware monitoring features of the SCH311x chips can only be accessed via the ISA bus. The driver therefore registers as a platform driver, if such a chip is detected.
