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

Pull ARM SoC cleanup from Olof Johansson:
 "Here is a collection of cleanup patches.  Among the pieces that stand
  out are:

   - The deletion of h720x platforms
   - Split of at91 non-dt platforms to their own Kconfig file to keep
     them separate
   - General cleanups and refactoring of i.MX and MXS platforms
   - Some restructuring of clock tables for OMAP
   - Convertion of PMC driver for Tegra to dt-only
   - Some renames of sunxi -> sun4i (Allwinner A10)
   - ... plus a bunch of other stuff that I haven't mentioned"
