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

Pull "ARM: device tree work" from Arnd Bergmann:
 "Most of these patches convert code from using static platform data to
  describing the hardware in the device tree.  This is only the first
  half of the changes for v3.4 because a lot of patches for this topic
  came in the last week before the merge window.

  Signed-off-by: Arnd Bergmann <arnd@arndb.de>"

Fix up trivial conflicts in arch/arm/mach-vexpress/{Kconfig,core.h}
