Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux

Pull thermal management update from Zhang Rui:
 "Highlights:

   - Introduction of thermal policy support, together with three new
     thermal governors, including step_wise, user_space, fire_share.

   - Introduction of ST-Ericsson db8500_thermal driver and ST-Ericsson
     db8500_cpufreq_cooling driver.

   - Thermal Kconfig file and Makefile refactor.

   - Fixes for generic thermal layer, generic cpucooling, rcar thermal
     driver and Exynos thermal driver."

+* ST-Ericsson DB8500 Thermal
+
+** Thermal node properties:
+
+- compatible : "stericsson,db8500-thermal";
+- reg : address range of the thermal sensor registers;
+- interrupts : interrupts generated from PRCMU;
+- interrupt-names : "IRQ_HOTMON_LOW" and "IRQ_HOTMON_HIGH";
+- num-trips : number of total trip points, this is required, set it 0 if none,
+  if greater than 0, the following properties must be defined;
+- tripN-temp : temperature of trip point N, should be in ascending order;
+- tripN-type : type of trip point N, should be one of "active" "passive" "hot"
+  "critical";
+- tripN-cdev-num : number of the cooling devices which can be bound to trip
+  point N, this is required if trip point N is defined, set it 0 if none,
+  otherwise the following cooling device names must be defined;
+- tripN-cdev-nameM : name of the No. M cooling device of trip point N;
+
+Usually the num-trips and tripN-*** are separated in board related dts files.
+
+Example:
