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."
