Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux

Pull thermal management fixes from Zhang Rui:
 "Specifics:

 - several fixes and cleanups on Rockchip thermal drivers.

 - add the missing support of RK3368 SoCs in Rockchip driver.

 - small fixes on of-thermal, power_allocator, rcar driver, IMX, and
   QCOM drivers, and also compilation fixes, on thermal.h, when thermal
   is not selected"

* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
  imx: thermal: use CPU temperature grade info for thresholds
  thermal: fix thermal_zone_bind_cooling_device prototype
  Revert "thermal: qcom_spmi: allow compile test"
  thermal: rcar_thermal: remove redundant operation
  thermal: of-thermal: Reduce log level for message when can't fine thermal zone
  thermal: power_allocator: Use temperature reading from tz
  thermal: rockchip: Support the RK3368 SoCs in thermal driver
  thermal: rockchip: consistently use int for temperatures
  thermal: rockchip: Add the sort mode for adc value increment or decrement
  thermal: rockchip: improve the conversion function
  thermal: rockchip: trivial: fix typo in commit
  thermal: rockchip: better to compatible the driver for different SoCs
  dt-bindings: rockchip-thermal: Support the RK3368 SoCs compatible
