Merge tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: More device tree support updates" from Olof Johansson:
 "This branch contains a number of updates for device tree support on
  several ARM platforms, in particular:

   * AT91 continues the device tree conversion adding support for a
     number of on-chip drivers and other functionality
   * ux500 adds probing of some of the core SoC blocks through device
     tree
   * Initial device tree support for ST SPEAr600 platforms
   * kirkwood continues the conversion to device-tree probing"

Manually merge arch/arm/mach-ux500/Kconfig due to MACH_U8500 rename, and
drivers/usb/gadget/at91_udc.c due to header file include cleanups.

Also do an "evil merge" for the MACH_U8500 config option rename that the
affected RMI4 touchscreen driver in staging.  It's called MACH_MOP500
now, and it was missed during previous merges.
