Merge tag 'soc-arm-7.4' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC board file updates from Arnd Bergmann:
 "These are mostly smaller cleanups for the remaining platform code in
  arch/arm/, the most notable one being the conversion of the
  s3c/crag6410 board to use software nodes for GPIO references in place
  of plain GPIO numbers.

  The earlier plan was to drop the deprecated (since 7.3) board files
  here, which would have been a much larger set of changes, but that is
  now deferred to 7.5"
