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

Pull ARM SoC cleanups from Arnd Bergmann:
 "This time around, the cleanup branch contains mostly code removal.  A
  number of board files for at91, imx and msm have become obsolete
  because of the DT conversion and are now ready to be removed.  The
  OMAP platform has traditionally had its own DMA engine abstraction and
  as this is being phased out, a lot of the original code is now unused
  and can be removed as well.

  S3C24xx can be simplified now that the restart code is a proper device
  driver.

  Finally, a number of cleanups in shmobile are done to prepare for the
  addition of new code in other branches"
