[PATCH 00/13] Thermal Framework Enhancements

[Durgadoss R <durgadoss.r@intel.com>]

This patch series attempts to enhance the thermal framework
by adding some simple governors/throttling algorithms.

These patches are based on Rui's tree here: (branch - thermal)
git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux.git

Patch 1: Refactor thermal.h so that it is easy to read/maintain
Patch 2: Move data structures that need to be visible to thermal.h
Patch 3: Adds some APIs to thermal_sys.c
Patch 4: Adds required platform layer information to thermal.h
Patch 5: Adds code to thermal_sys, that can retrieve platform data
         (if provided) for a thermal zone
Patch 6: Creates a policy sysfs attribute (RO, for now)
Patch 7: Modifies the bind/unbind logic based on the platform data
	 With this modification, the bind/unbind can work with or
	 without platform data
Patch 8: Introduces a fair_share governor. This throttles the
	 cooling_devices according to their weights. The weights
	 in turn describe the effectiveness of a particular
	 cooling device in cooling a thermal zone.
Patch 9: Introduce step_wise governor
	 This throttles/de-throttles the cooling devices one
	 step at a time. This is exactly similar to the code
	 we have in thermal_zone_device_update function. The
	 intention is to move all 'throttling logic' related
	 code outside thermal_sys.c and keep them separate.
Patch 10: Removes all throttling code outside thermal_sys.c
Patch 11: Adds a notification API so that thermal sensor drivers
	  can notify the framework of any thermal events.
Patch 12: Adds documentation to Documentation/thermal/sysfs-api.txt
Patch 13: Shows some sample code on how to provide platform level
	  thermal data. This patch is not for merge.
