Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC fixes from Olof Johansson:
 "A collection of fixes for ARM platforms.  Most are fixes for DTS
  files, mostly from DT conversion on OMAP which is still finding a few
  issues here and there.

  There's a couple of small stale code removal patches that we usually
  queue for the next release instead, but they seemed harmless enough to
  bring in now.

  Also, a fix for backlight on some PXA platforms, and a cache
  configuration fix for Tegra, etc"
