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

Pull ARM SoC power management and clock changes from Olof Johansson:
 "This branch contains a largeish set of updates of power management and
  clock setup.  The bulk of it is for OMAP/AM33xx platforms, but also a
  few around hotplug/suspend/resume on Exynos.

  It includes a split-up of some of the OMAP clock data into separate
  files which adds to the diffstat, but gross delta is fairly reasonable."
