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

Pull ARM SoC fixes from Olof Johansson:
 "This is a slightly larger batch of fixes that we've been sitting on a
  few -rcs.  Most of them are simple oneliners, but there are two sets
  that are slightly larger and worth pointing out:

   - A set of patches to OMAP to deal with hwmod for RTC on am33xx
     (beaglebone SoC, among others).  It's the only clock that ever has
     a valid offset of 0, so a new flag needed introduction once this
     problem was discovered.

   - A collection of CCI fixes for performance counters discovered once
     people started using it on X-Gene CPUs"
