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 branch contains code cleanups, moves and removals for 3.13.

  Qualcomm msm targets had a bunch of code removal for legacy non-DT
  platforms.  Nomadik saw more device tree conversions and cleanup of
  old code.  Tegra has some code refactoring, etc.

  One longish patch series from Sebastian Hasselbarth changes the
  init_time hooks and tries to use a generic implementation for most
  platforms, since they were all doing more or less the same things.

  Finally the "shark" platform is removed in this release.  It's been
  abandoned for a while and nobody seems to care enough to keep it
  around.  If someone comes along and wants to resurrect it, the removal
  can easily be reverted and code brought back.

  Beyond this, mostly a bunch of removals of stale content across the
  board, etc"
