2008-08-15hwmon-vid: Fix AMD K8 VID decodingJean Delvare
Not all AMD K8 have 6 VID pins, contrary to what was assumed in commit 116d0486bdefc11f71e567cadf0c47f788b4dd06. This commit broke support of older CPU models which have only 5 VID pins: http://bugzilla.kernel.org/show_bug.cgi?id=11329 We need two entries in the hwmon-vid table, one for 5-bit VID models (K8 revision <= E) and one for 6-bit VID models (K8 revision >= F). This fixes bug #11329.

2008-08-15ibmaem: don't query the entire sensor repository when reading energy meterDarrick J. Wong
Currently, all sensors are read when the energy meter is queried via sysfs. This introduces a considerable amount of delay and variation in the sysfs reading, which is not desirable when trying to profile energy use. Therefore, read only the energy meters when a sysfs query comes in for them, and don't cache the results so that we always get the latest reading. Signed-off-by: Darrick J.

2008-08-15ibmaem: prevent infinite probing loop on x3650 M2 systemsDarrick J. Wong
On older machines, probing for a nonexistent AEM interface returned an IPMI error; when we saw this, we'd stop probing. On the x3650 M2 and (presumably) later, we are returned a value indicating success and a buffer full of garbage or zeroes. This causes the probe function to run in an infinite loop. To fix this, we add one last check--if the interface number we're looking for is higher than the number of interfaces that AEM claims to have, stop probing. Signed-off-by: Darrick J.

2008-08-15abituguru3: prefer DMI probing to manual probingAlistair John Strachan
Previously the driver was only using DMI to prevent smbus probing on non-Abit motherboards. However, since the manual probing method is brittle and prone to failure on some Abit motherboards (esp. the Abit IP35 Pro) it is better to use DMI to also read the board name and then decide whether or not to probe the bus. At the moment, we do not have a list of valid DMI name strings to use for existing and supported motherboards. This patch only implements DMI probing for the IP35 Pro. For motherboards that can not yet use DMI probing, a warning will be printed to the kernel log asking those users to email me their dmidecode output. The existing manual probing mechanism will be used if CONFIG_DMI is not enabled, if DMI probing fails (for DMI-unsupported motherboards), or if DMI probing fails and the "force" option is set (for DMI-supported motherboards). Ideally in the longer term this manual probing method would be removed. This patch should be safe to apply as it does not change the probing behaviour for most of the supported motherboards, just the IP35 Pro, which already has regressions filed against it in 2.6.26.

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.

Clean up and simplify the device initialization function: * Degrade error messages to warnings - what they really are. * Stop warning about VxI mode, we don't really care. * Drop comment about lack of limit initialization - that's the standard way, all hardware monitoring drivers do that. * Only read the configuration register once. * Only write back to the configuration register if needed. * Don't attempt to clear the lock bit, it locks itself to 1. * Move the function to before it's called, so that we no longer need to forware declare it.

2008-07-31hwmon: (lm75) add new-style driver bindingDavid Brownell
More LM75 updates: - Teach the LM75 driver to use new-style driver binding: * Create a second driver struct, using new-style driver binding methods cribbed from the legacy code. * Add a MODULE_DEVICE_TABLE (for "newER-style binding") * The legacy probe logic delegates its work to this new code. * The legacy driver now uses the name "lm75_legacy". - More careful initialization. Chips are put into 9-bit mode so the current interconversion routines will never fail. - Save the original chip configuration, and restore it on exit. (Among other things, this normally turns off the mode where the chip is constantly sampling ... and thus saves power.) So the new-style code should catch all chips that boards declare, while the legacy code catches others. This particular coexistence strategy may need some work yet ... legacy modes might best be set up explicitly by some tool not unlike "sensors-detect". (Or else completely eradicated...)

One driver binding function moved out of the attribute section, as did the driver struct itself. - Minor tweaks to legacy probe logic: correct a comment, and remove a pointless variable. - Whitespace, linelength, and comment fixes.
