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

Pull thermal management updates from Zhang Rui:
 "The top merge commit was re-generated yesterday because two topic
  branches were dropped from this pull request in the last minute due to
  some unaddressed comments.  All the other material has been in
  linux-next for quite a while.

  Specifics:

   - Enhance thermal core to handle unexpected device cooling states
     after fresh boot and system resume.  From Zhang Rui and Chen Yu.

   - Several fixes and cleanups on Rockchip and RCAR thermal drivers.
     From Caesar Wang and Kuninori Morimoto.

   - Add Broxton support for Intel processor thermal reporting device
     driver.  From Amy Wiles"
