Merge tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux-2.6

Pull device tree changes from Grant Likely:
 "Here are the DT changes I've got queued up for v3.8.  As described
  below, there are a lot of bug fixes here and documentation updates but
  nothing major:

  Bug fixes, little cleanups, and documentation changes.  The most
  invasive thing here touches a bunch of the arch directories to use a
  common build rule for .dtb files.  There are no major changes to
  functionality here other than a few new helper functions."
