The hysteresis register is shared among both temperature sensors.
This means changing one also affects the other. To avoid confusion,
established way to express this is to make only the first instance writable
and keep all other instances as read-only. Otherwise users may be
confused that changing the second writable value also affects the first,
while it is more obvious that a writable value may affect a different
read-only value.Signed-off-by: Guenter Roeck

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.Signed-off-by: Arnaud Ebalard

Basically it's the same as the original DS75 but much faster.
Signed-off-by: Jean Delvare
Acked-by: Guenter Roeck -
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.Signed-off-by: Jean Delvare

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.Minor changes, but still worth mentioning:
- Battery temperature reporting fix for Nokia N900 phones
- Versatile Express poweroff driver moved into drivers/power/reset/
