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

Pull ARM SoC cleanups and fixes from Arnd Bergmann:
 "Traditionally we've had two separate branches for cleanups and
  non-critical bug fixes, but both of these got smaller with each
  release and the differences are rather unclear now, so it seems more
  appropriate to have a combined branch.

  The most notable change is for OMAP, which gets a small rework to
  simplify handling of the AUXDATA mechanism used on machines that are
  not completely DT based yet, along with other work that is used as
  preparation for dropping the legacy board files"
