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
  ...
