* hwmon: (w83793) Saving negative errors in unsignedDan Carpenter2010-03-29

| | | | | | | | | | | | | | | | Before switching to automatic fan control mode, make sure that all the trip points make sense. Otherwise, the control loop could lead to weird fan behavior. Signed-off-by: Jean Delvare <khali@linux-fr.org>
| * hwmon: (it87) Add support for old automatic fan speed controlJean Delvare2010-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the automatic fan speed control interface as implemented by IT8705F chips up to revision F and IT8712F chips up to revision G. This implementation fits very well in our standard sysfs interface. I implemented the old and not the new interface because the only chip I have at hand is an old one, and the new interface is more difficult to map to the standard sysfs interface. Adding support later should be possible though, if someone with a supported chip is interested. Signed-off-by: Jean Delvare <khali@linux-fr.org>

| * hwmon: (it87) Refactor attributes creation and removalJean Delvare2010-03-05
| | | | | | | | | | | | | | | | | | | | | | | | There is a lot of code redundancy in the creation of the fan and pwm attributes. Move these attributes to arrays so that the code can be simplified. This in turns makes the attributes removal code larger, so move it to a separate function that can be called in both the standard removal case and the error path during probing.

| * hwmon: (it87) Expose the PWM/temperature mappingsJean Delvare2010-03-05
| | | | | | | | | | | | | | | | | | Let the user read the PWM-to-temperature mappings. Until the trip points are also exposed, this is essentially a way to know how the BIOS has set things up. The ability to change the settings will be added later, together with the trip points. Signed-off-by: Jean Delvare <khali@linux-fr.org>

| | | | | | | | | | | | | | | | | | The it87 driver doesn't yet support automatic fan control. Let it at least tell the user when a fan output is in automatic mode. Also let the user switch from automatic mode (possibly set by the BIOS) to manual mode and back without losing the settings. Signed-off-by: Jean Delvare <khali@linux-fr.org>
| * hwmon: (lm90) Add SMBus alert supportJean Delvare2010-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Tested successfully with an ADM1032 chip on its evaluation board. It should work fine with all other chips as well. At this point this is more of a proof-of-concept, we don't do anything terribly useful on SMBus alert: we simply log the event. But this could later evolve into libsensors signaling so that user-space applications can take an appropriate action.

| * hwmon: (w83781d) Request I/O ports individually for probingJean Delvare2010-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Different motherboards have different PNP declarations for W83781D/W83782D chips. Some declare the whole range of I/O ports (8 ports), some declare only the useful ports (2 ports at offset 5) and some declare fancy ranges, for example 4 ports at offset 4. To properly handle all cases, request all ports individually for probing. After we have determined that we really have a W83781D or W83782D chip, the useful port range will be requested again, as a single block. I did not see a board which needs this yet, but I know of one for lm78 driver and I'd like to keep the logic of these two drivers in sync.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The #define ADT7462_VOLT_COUNT is wrong, it should be 13 not 12. All the for loops that use this as a limit count are of the typical form, "for (n = 0; n < ADT7462_VOLT_COUNT; n++)", so to loop through all voltages w/o missing the last one it is necessary for the count to be one greater than it is. (Specifically, you will miss the +1.5V 3GPIO input with count = 12 vs. 13.) Signed-off-by: Ray Copeland <ray.copeland@aprius.com> Acked-by: "Darrick J.

* | macintosh/hwmon/ams: Fix device removal sequenceJean Delvare2010-02-03
|/ | | | | | | | | | | | | | | | | | Some code that is in ams_exit() (the module exit code) should instead be called when the device (not module) is removed. It probably doesn't make much of a difference in the PMU case, but in the I2C case it does matter. I make no guarantee that my fix isn't racy, I'm not familiar enough with the ams driver code to tell for sure.
