Merge branch 'ux500/dt' into next/dt2
* ux500/dt:
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: ux500: fix compilation after local timer rework
(adds dependency on localtimer branch, irqdomain branch and ux500/soc
branch)
Conflicts:
arch/arm/mach-ux500/devices-common.c
This adds patches from Lee Jones, Niklas Hernaeus and myself to provide
initial device tree support on the ux500 platform. The pull request from
Lee contained some other changes, so I rebased the patches on top of
the branches that are actually dependencies for this.
