Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management updates from Zhang Rui: "Highlights: - introduction of Dove thermal sensor driver. - introduction of Kirkwood thermal sensor driver. - introduction of intel_powerclamp thermal cooling device driver. - add interrupt and DT support for rcar thermal driver. - add thermal emulation support which allows platform thermal driver to do software/hardware emulation for thermal issues." * 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: (36 commits) thermal: rcar: remove __devinitconst thermal: return an error on failure to register thermal class Thermal: rename thermal governor Kconfig option to avoid generic naming thermal: exynos: Use the new thermal trend type for quick cooling action. Thermal: exynos: Add support for temperature falling interrupt. Thermal: Dove: Add Themal sensor support for Dove. thermal: Add support for the thermal sensor on Kirkwood SoCs thermal: rcar: add Device Tree support thermal: rcar: remove machine_power_off() from rcar_thermal_notify() thermal: rcar: add interrupt support thermal: rcar: add read/write functions for common/priv data thermal: rcar: multi channel support thermal: rcar: use mutex lock instead of spin lock thermal: rcar: enable CPCTL to use hardware TSC deciding thermal: rcar: use parenthesis on macro Thermal: fix a build warning when CONFIG_THERMAL_EMULATION cleared Thermal: fix a wrong comment thermal: sysfs: Add a new sysfs node emul_temp for thermal emulation PM: intel_powerclamp: off by one in start_power_clamp() thermal: exynos: Miscellaneous fixes to support falling threshold interrupt ...

+* Dove Thermal
+
+This driver is for Dove SoCs which contain a thermal sensor.
+
+Required properties:
+- compatible : "marvell,dove-thermal"
+- reg : Address range of the thermal registers
+
+The reg properties should contain two ranges. The first is for the
+three Thermal Manager registers, while the second range contains the
+Thermal Diode Control Registers.
+
+Example:
+
+ thermal@10078 {
+ compatible = "marvell,dove-thermal";
+ reg = <0xd001c 0x0c>, <0xd005c 0x08>;
+ };

+* Kirkwood Thermal
+
+This version is for Kirkwood 88F8262 & 88F6283 SoCs. Other kirkwoods
+don't contain a thermal sensor.

+* Renesas R-Car Thermal
+
+Required properties:
+- compatible : "renesas,rcar-thermal"
+- reg : Address range of the thermal registers.
+ The 1st reg will be recognized as common register
+ if it has "interrupts".

+Option properties:
+
+- interrupts : use interrupt

+Example (non interrupt support):
+
+thermal@e61f0100 {
+ compatible = "renesas,rcar-thermal";
