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 batch of fixes for ARM SoCs for 3.13.  The diffstat is large,
  mostly because of:

   - Another set of fixes to fix regressions caused by moving OMAP from
     board files to DT.  Tony thinks this was the last major set of
     fixes, with maybe just a few small patches to follow.
   - More fixes for Marvell platforms, most dealing with misdescribed
     PCIe hardware, i.e.  incorrect number of busses on some SoCs, etc.
     The line delta adds up due to various ranges moving around when
     this is fixed.

  But there's also:

   - Some smaller tweaks to defconfigs to make more boards bootable in
     my test setup for better coverage.
   - There are also a few other smaller fixes, a short series for at91,
     a couple of reverts for ux500, etc"
