GMT G762/763 fan speed PWM controller is connected directly to a fan and performs closed-loop or open-loop control of the fan speed. Two modes - PWM or DC - are supported by the chip. Introduced driver provides various knobs to control the operations of the chip (via sysfs interface). Specific characteristics of the system can be passed either using board init code or via DT. Documentation for both the driver and DT bindings are also provided.

2013-05-04hwmon: (lm75) Tune resolution and sample time per chipJean Delvare1-3/+4
Most LM75-compatible chips can either sample much faster or with a much better resolution than the original LM75 chip. So far the lm75 driver did not let the user take benefit of these improvements. Do it now. I decided to almost always configure the chip to use the best resolution possible, which also means the longest sample time. The only chips for which I didn't are the DS75, DS1775 and STDS75, because they are really too slow in 12-bit mode (1.2 to 1.5 second worst case) so I went for 11-bit mode as a more reasonable tradeoff. This choice is dictated by the fact that the hwmon subsystem is meant for system monitoring, it has never been supposed to be ultra-fast, and as a matter of fact we do cache the sampled values in almost all drivers. If anyone isn't pleased with these default settings, they can always introduce a platform data structure or DT support for the lm75. That being said, it seems nobody ever complained that the driver wouldn't refresh the value faster than every 1.5 second, and the change made it faster for all chips even in 12-bit mode, so I don't expect any complaint.

Pull battery updates from Anton Vorontsov: "Highlights: - OpenFirmware/DeviceTree support for the Power Supply core: the core now automatically populates supplied_from hierarchy from the device tree. With these patches chargers and batteries can now lookup each other without the board files support shim. Rhyland Klein at NVIDIA did the work - New ST-Ericsson ABX500 hwmon driver. The driver is heavily using the AB85xx core and depends on some recent changes to it, so that is why the driver comes through the battery tree. It has an appropriate ack from the hwmon maintainer (i.e. Guenter Roeck). Martin Persson at ST-Ericsson and Hongbo Zhang at Linaro authored the driver - Final bits to sync AB85xx ST-Ericsson changes into mainline. The changes touch mfd parts, but these were acked by the appropriate MFD maintainer (ie Samuel Ortiz). Lee Jones at Linaro did most of the work and lead the submission process.

Output current attributes supported on LTC3880 were described as providing input current values. Fix text to reflect that the attributes provide output current values. "reset history" attribute descriptions were misleading and seemed to imply that all history was reset when writing a single attribute. Replace with more accurate text. Replace 'internal temperature" with "chip temperature". Temperature limits not only apply to the chip temperature, but also to external temperatures on LTC3880, so remove the word "chip" from the attribute description.

2013-04-07hwmon: (adt7410) Add support for the adt7310/adt7320Lars-Peter Clausen1-17/+30
The adt7310/adt7320 is the SPI version of the adt7410/adt7420. The register map layout is a bit different, i.e. the register addresses differ between the two variants, but the bit layouts of the individual registers are identical. So both chip variants can easily be supported by the same driver. The issue of non matching register address layouts is solved by a simple look-up table which translates the I2C addresses to the SPI addresses. The patch moves the bulk of the adt7410 driver to a common module that will be shared by the adt7410 and adt7310 drivers. This common module implements the driver logic and uses a set of virtual functions to perform IO access. The adt7410 and adt7310 driver modules provide proper implementations of these IO accessor functions for I2C respective SPI.
