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

Pull ARM SoC driver updates from Olof Johansson:
 "These are changes for drivers that are intimately tied to some SoC and
  for some reason could not get merged through the respective subsystem
  maintainer tree.

  This time around, much of this is for at91, with the bulk of it being
  syscon and udc drivers.

  Also, there's:
   - coupled cpuidle support for Samsung Exynos4210
   - Renesas 73A0 common-clk work
   - of/platform changes to tear down DMA mappings on device destruction
   - a few updates to the TI Keystone knav code"
