Linus Torvalds cf4af01221 ARM: arm-soc: Board updates for 3.8
This branch contains a set of various board updates for ARM platforms.
 
 A few shmobile platforms that are stale have been removed, some
 defconfig updates for various boards selecting new features such as
 pinctrl subsystem support, and various updates enabling peripherals, etc.

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

Pull ARM SoC board updates from Olof Johansson:
 "This branch contains a set of various board updates for ARM platforms.

  A few shmobile platforms that are stale have been removed, some
  defconfig updates for various boards selecting new features such as
  pinctrl subsystem support, and various updates enabling peripherals,
  etc."

Fix up conflicts mostly as per Olof.
