Merge tag 'devicetree-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/glikely/linux

Pull devicetree updates from Grant Likely:
 "A whole lot of bug fixes.

  Nothing stands out here except the ability to enable CONFIG_OF on
  every architecture, and an import of a newer version of dtc"
