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

Pull thermal management updates from Zhang Rui:

 - add thermal driver for R-Car Gen3 thermal sensors.

 - add thermal driver for ZTE' zx2967 family thermal sensors.

 - convert thermal ID allocation from IDR to IDA.

 - fix a possible NULL dereference in imx thermal driver.

 - fix a ti-soc-thermal driver dependency issue so that critical thermal
   control is still available when CPU_THERMAL is not defined.

 - update binding information for QorIQ thermal driver.

 - a couple of cleanups in thermal core, intel_powerclamp, exynos,
   dra752-thermal, mtk-thermal driver.
