PATCH 1) [thermal: Add a new trip type to use cooling device instance number] This patch adds a new trip type THERMAL_TRIP_STATE_ACTIVE which passes cooling device instance number and may be helpful for cpufreq cooling devices to take the correct cooling action. PATCH 2) [thermal: Add generic cpu cooling implementation] This patch adds generic cpu cooling low level implementation through frequency clipping and cpu hotplug. In future, other cpu related cooling devices may be added here. An ACPI version of this already exists(drivers/acpi/processor_thermal.c). But this will be useful for platforms like ARM using the generic thermal interface along with the generic cpu cooling devices. The cooling device registration API's return cooling device pointers which can be easily binded with the thermal zone trip points.
