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 the branch where we usually queue up cleanup efforts, moving
  drivers out of the architecture directory, header file restructuring,
  etc.  Sometimes they tangle with new development so it's hard to keep
  it strictly to cleanups.

  Some of the things included in this branch are:

   * Atmel SAMA5 conversion to common clock
   * Reset framework conversion for tegra platforms
    - Some of this depends on tegra clock driver reworks that are shared
      with Mike Turquette's clk tree.
   * Tegra DMA refactoring, which are shared branches with the DMA tree.
   * Removal of some header files on exynos to prepare for
     multiplatform"
