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.
