* 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. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
