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

Pull thermal updates from Zhang Rui:
 "Specifics:

   - adds full support for 2 types of Thermal Controllers produced by
     STMicroelectronics.  One is a more traditional memory mapped
     variant, the other is controlled solely by system configuration
     registers.  From Lee Jones.

   - add TMU (Thermal Management Unit) support for Exynos3250 Soc.
     From Chanwoo Choi.

   - add critical and passive trip point support for int3403 thermal
     driver.  From Srinivas Pandruvada.

   - a couple of small fixes/cleanups from Javi Merino, and Geert
     Uytterhoeven"

* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
  thermal: document struct thermal_zone_device and thermal_governor
  thermal: cpu_cooling: fix typo highjack -> hijack
  thermal: rcar: Document SoC-specific bindings
  thermal: samsung: Add TMU support for Exynos3250 SoC
  thermal: exynos: fix ordering in exynos_tmu_remove()
  thermal: allow building dove_thermal with mvebu
  thermal: sti: Add support for ST's Memory Mapped based Thermal controller
  thermal: sti: Add support for ST's System Config Register based Thermal controller
  thermal: sti: Introduce ST Thermal core code
  thermal: sti: Supply Device Tree documentation
  Thermal: int3403: Add CRT and PSV trip
