29b19e2504 Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux into thermal
Conflicts:
	drivers/staging/omap-thermal/omap-thermal-common.
		OMAP supplied dummy TC1 and TC2,
		at the same time that the thermal tree removed them
		from thermal_zone_device_register()

	drivers/thermal/cpu_cooling.c b/drivers/thermal/cpu_cooling.c
		propogate the upstream MAX_IDR_LEVEL re-name
			to prevent a build failure

c48cbba6fe hwmon: exynos4: move thermal sensor driver to driver/thermal directory
This movement is needed because the hwmon entries and corresponding sysfs
interface is a duplicate of utilities already provided by
driver/thermal/thermal_sys.c.  The goal is to place it in thermal folder
and add necessary functions to use the in-kernel thermal interfaces.

312869ec93 hwmon: (sch56xx) Add support for the integrated watchdog (v2)
Add support for the watchdog integrated into the SMSC SCH5627 and
SCH5636 superio-s. Since the watchdog is part of the hwmon logical device
and thus shares ioports with it, the watchdog driver is integrated into the
existing hwmon drivers for these.

Note that this version of the watchdog support for sch56xx superio-s
implements the watchdog chardev interface itself, rather then relying on
the recently added watchdog core / watchdog_dev. This is done because
currently some needed functionality is missing from watchdog_dev, as soon
as this functionality is added (which is being discussed on the
linux-watchdog mailinglist), I'll convert this driver over to using
watchdog_dev.

f22aaaa70d hwmon: Driver for NTC Thermistors
Add support for NTC Thermistor series. In this release, the
following thermistors are supported: NCP15WB473, NCP18WB473, NCP03WB473,
and NCP15WL333. This driver is based on the datasheet of MURATA.

The driver in the patch does conversion from the raw ADC value
(either voltage or resistence) to temperature. In order to use
voltage values as input, the circuit schematics should be provided
with the platform data. A compensation table for each type of thermistor
is provided for the conversion.

0772a64079 hwmon: New driver sch5636
This patch adds a new driver for SMSC SCH5636 Super I/O chips.
The chips include an embedded microcontroller for hardware monitoring
solutions, allowing motherboard manufacturers to create their own
custom hwmon solution based upon the SCH5636.

Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636
based hwmon solution. The sch5636 driver runs a sanity check on
loading to ensure it is dealing with a Fujitsu Theseus and not with
another custom SCH5636 based hwmon solution.

ec693fe528 hwmon: (abituguru) Depend on DMI
The abituguru drivers are only built on X86, where DMI support is now
enabled by default. So let these drivers depend on DMI, for the
following gains:
* Robustness and safety. Detection of these devices is weak and uses
  non-standard methods, it should really be limited to Abit boards
  unless the user explicitly asks otherwise.
* Code simplicity. The code is easier to read without ifdefs.
* Better build testing coverage. Now there's only one way to build the
  drivers, so no risk of build failure on exotic systems.

7d03336538 Move ACPI power meter driver to hwmon
As discussed earlier, the ACPI power meter driver would better live
in drivers/hwmon, as its only purpose is to create hwmon-style
interfaces for ACPI 4.0 power meter devices. Users are more likely to
look for it there, and less likely to accidentally hide it by
unselecting its dependencies.
