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

Pull ARM SoC late OMAP changes from Olof Johansson:
 "This branch contains changes for OMAP that came in late during the
  release staging, close to when the merge window opened.

  It contains, among other things:

   - OMAP PM fixes and some patches for audio device integration
   - OMAP clock fixes related to common clock conversion
   - A set of patches cleaning up WFI entry and blocking.
   - A set of fixes and IP block support for PM on TI AM33xx SoCs
     (Beaglebone, etc)
   - A set of smaller fixes and cleanups around AM33xx restart and
     revision detection, as well as removal of some dead code
     (CONFIG_32K_TIMER_HZ)"
