Linus Torvalds b58ed041a3 Device tree changes for v3.8
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 ew new helper functions.

 "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:
