Merge tag 'cleanup-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc into next

Pull ARM SoC cleanups from Olof Johansson:
 "Cleanups for 3.16.  Among these are:

   - a bunch of misc cleanups for Broadcom platforms, mostly
     housekeeping
   - enabling Common Clock Framework on the older s3c24xx Samsung
     chipsets
   - cleanup of the Versatile Express system controller code, moving it
     to syscon
   - power management cleanups for OMAP platforms

  plus a handful of other cleanups across the place"
