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. * tag 'dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (48 commits) ARM: SPEAr600: Add device-tree support to SPEAr600 boards ARM: ux500: Provide local timer support for Device Tree ARM: ux500: Enable PL022 SSP Controller in Device Tree ARM: ux500: Enable PL310 Level 2 Cache Controller in Device Tree ARM: ux500: Enable PL011 AMBA UART Controller for Device Tree ARM: ux500: Enable Cortex-A9 GIC (Generic Interrupt Controller) in Device Tree ARM: ux500: db8500: list most devices in the snowball device tree ARM: ux500: split dts file for snowball into generic part ARM: ux500: combine the board init functions for DT boot ARM: ux500: Initial Device Tree support for Snowball ARM: ux500: CONFIG: Enable Device Tree support for future endeavours ARM: kirkwood: use devicetree for rtc-mv ARM: kirkwood: rtc-mv devicetree bindings ARM: kirkwood: fdt: define uart[01] as disabled, enable uart0 ARM: kirkwood: fdt: facilitate new boards during fdt migration ARM: kirkwood: fdt: absorb kirkwood_init() ARM: kirkwood: fdt: use mrvl ticker symbol ARM: orion: wdt: use resource vice direct access ARM: Kirkwood: Remove tclk from kirkwood_asoc_platform_data.
