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

Pull ARM SoC cleanups from Olof Johansson:
 "This is a good healthy set of various code removals.  Total net delta
  is 8100 lines removed.

  Among the larger cleanups are:

   - Removal of old Samsung S3C DMA infrastructure by Arnd
   - Removal of the non-DT version of the 'lager' board by Magnus Damm
   - General stale code removal on OMAP and Davinci by Rickard Strandqvist
   - Removal of non-DT support on am3517 platforms by Tony Lindgren

  ... plus several other cleanups of various platforms across the board"
