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

Pull device tree conversions for arm-soc, part 1, from Olof Johansson:
 "The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game
  of booting using device trees, which is a great step forward for them.
  at91 and spear have pretty much completed this process with a huge
  amount of work being put into at91.  The other platforms are
  continuing the process.

  We finally start to see the payback on this investment, as new
  machines are getting supported purely by adding a .dts source file
  that can be completely independent of the kernel source."

Fix up trivial conflict in arch/arm/Kconfig
