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 ...
