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

Pull ARM SoC fixes from Olof Johansson:
 "Another week, another batch of fixes.

  Again, OMAP regressions due to move to DT is the bulk of the changes
  here, but this should be the last of it for 3.13.  There are also a
  handful of OMAP hwmod changes (power management, reset handling) for
  USB on OMAP3 that fixes some longish-standing bugs around USB resets.

  There are a couple of other changes that also add up line count a bit:
  One is a long-standing bug with the keyboard layout on one of the PXA
  platforms.  The other is a fix for highbank that moves their
  power-off/reset button handling to be done in-kernel since relying on
  userspace to handle it was fragile and awkward"
