Merge tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC multiplatform code updates from Arnd Bergmann:
 "This branch is the culmination of 5 years of effort to bring the ARMv6
  and ARMv7 platforms together such that they can all be enabled and
  boot the same kernel.  It has been a tremendous amount of cleanup and
  refactoring by a huge number of people, and creation of several new
  (and major) subsystems to better abstract out all the platform details
  in an appropriate manner.

  The bulk of this branch is a large patchset from Arnd that brings
  several of the more minor and older platforms we have closer to
  multiplatform support.  Among these are MMP, S3C64xx, Orion5x, mv78xx0
  and realview Much of this is moving around header files from old mach
  directories, but there are also some cleanup patches of debug_ll
  (lowlevel debug per-platform options) and other parts.

  Linus Walleij also has some patchs to clean up the older ARM Realview
  platforms by finally introducing DT support, and Rob Herring has some
  for ARM Versatile which is now DT-only.  Both of these platforms are
  now multiplatform.

  Finally, a couple of patches from Russell for Dove PMU, and a fix from
  Valentin Rothberg for Exynos ADC, which were rebased on top of the
  series to avoid conflicts"
