Commit 3d883483 authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal

Pull more thermal managament updates from Zhang Rui:
 "Specifics:

   - Exynos thermal driver refactoring.  Several cleanups, code
     optimization, unused symbols removal, and unused feature removal in
     Exynos thermal driver.  Thanks Lukasz for this effort.

   - Exynos thermal driver support to OF thermal.  After the code
     refactoring, the driver earned the support to OF thermal.  Chip
     thermal data were moved from driver code to DTS, reducing the code
     footprint.  Thanks Lukasz for this.

   - After receiving the OF thermal support, the exynos thermal driver
     now must allow modular build.  Thanks Arnd for detecting, reporting
     and fixing this.

   - Exynos thermal driver support to Exynos 7 SoC.  Thanks Abhilash for
     this.

   - Accurate temperature reporting on Rockchip thermal driver, thanks
     to Caesar.

   - Fix on how OF thermal enables its zones, thanks Lukasz for fixing.

   - Fixes in OF thermal examples under Documentation/.  Thanks Srinivas
     for fixing"
