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

Pull arm soc-specific pinctrl changes from Olof Johansson:
 "With this, five platforms are moving to the relatively new pinctrl
  subsystem for their pin management, replacing the older soc specific
  in-kernel interfaces with common code.

  There is quite a bit of net addition of code for each platform being
  added to the pinctrl subsystem.  But the payback comes later when
  adding new boards can be done by only providing new device trees
  instead."

Fix up trivial conflicts in arch/arm/mach-ux500/{Makefile,board-mop500.c}
