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: 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
