Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM soc device tree updates from Olof Johansson:
 "Device tree conversion and enablement branch.  Mostly a bunch of new
  bindings and setup for various platforms, but the Via/Winchip VT8500
  platform is also converted over from being 100% legacy to now use
  device tree for probing.  More of that will come for 3.8."

Trivial conflicts due to removal of vt8500 files, and one documentation
file that was added with slightly different contents both here and in
the USb tree.
