Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal updates from Zhang Rui: - Implement generic devfreq cooling mechanism through frequency reduction for devices using devfreq. From Ørjan Eide and Javi Merino. - Introduce OMAP3 support on TI SoC thermal driver. From Pavel Mack and Eduardo Valentin. - A bounch of small fixes on devfreq_cooling, Exynos, IMX, Armada, and Rockchip thermal drivers. * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: (24 commits) thermal: exynos: Directly return 0 instead of using local ret variable thermal: exynos: Remove unneeded semicolon thermal: exynos: Use IS_ERR() because regulator cannot be NULL thermal: exynos: Fix first temperature read after registering sensor thermal: exynos: Fix unbalanced regulator disable on probe failure devfreq_cooling: return on allocation failure thermal: rockchip: support the sleep pinctrl state to avoid glitches in s2r dt-bindings: rockchip-thermal: Add the pinctrl states in this document thermal: devfreq_cooling: Make power a u64 thermal: devfreq_cooling: use a thermal_cooling_device for register and unregister thermal: underflow bug in imx_set_trip_temp() thermal: armada: Fix possible overflow in the Armada 380 thermal sensor formula thermal: imx: register irq handler later in probe thermal: rockhip: fix setting thermal shutdown polarity thermal: rockchip: fix handling of invalid readings devfreq_cooling: add trace information thermal: Add devfreq cooling PM / OPP: get the voltage for all OPPs tools/thermal: tmon: use pkg-config also for CFLAGS linux/thermal.h: rename KELVIN_TO_CELSIUS to DECI_KELVIN_TO_CELSIUS ...
