Pull thermal management updates from Zhang Rui:
"This time we only have a few changes as there are no soc thermal
changes from Eduardo. The only big change is the introduction of
TMON, a tool to help visualize, tune, and test the thermal subsystem.
The rest is mostly cleanups and fixes all over.
Specifics:
- introduce TMON, a tool base on thermal sysfs I/F. It can be used
to visualize, tune and test the thermal subsystem.
- fix a zone/cooling device binding problem, when both thermal zone
bind parameters and .bind() callback are available"
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
tools/thermal: Introduce tmon, a tool for thermal subsystem
thermal: Fix binding problem when there is thermal zone params
thermal: cpu_cooling: fix return value check in cpufreq_cooling_register()
Thermal: Check for validity before doing kfree
thermal/intel_powerclamp: Add newer CPU models
Thermal: Tidy up error handling in powerclamp_init
thermal: Kconfig: cosmetic fixes
ACPI/thermal : Remove zone disabled warning
typo in drivers/thermal/Kconfig: lpatform instead of platform

tristate "Generic Thermal sysfs driver"
|
|
help
|
|
Generic Thermal Sysfs driver offers a generic mechanism for
|
|
thermal management. Usually it's made up of one or more thermal
|
|
zone and cooling device.
|
|
Each thermal zone contains its own temperature, trip points,
|
|
cooling devices.
|
|
All platforms with ACPI thermal support can use this driver.
|
|
If you want this support, you should say Y or M here.

In case a sensor is registered with the thermal

WARNING: Be careful while enabling this option on production systems,

because userland can easily disable the thermal policy by simply

flooding this sysfs node with low temperature values.
