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

Pull arm-soc device tree description updates from Arnd Bergmann:
 "This branch contains two kinds of updates: Some platforms in the
  process of getting converted to device tree based booting, and the
  platform specific patches necessary for that are included here.

  Other platforms are already converted, so we just need to update the
  actual device tree source files and the binding documents to add
  support for new board and new drivers.

  In the future we will probably separate those into two branches, and
  in the long run, the plan is to move the device tree source files out
  of the kernel repository, but that has to wait until we have completed
  a much larger portion of the binding documents."

Fix up trivial conflicts in arch/arm/mach-imx/clk-imx6q.c due to newly
added clkdev registers next to a few removed unnecessary ones.
