Merge branch 'vexpress-dt-v3.3-rc4' of git://git.linaro.org/people/pawelmoll/linux into next/dt
* 'vexpress-dt-v3.3-rc4' of git://git.linaro.org/people/pawelmoll/linux: (573 commits) ARM: vexpress: Add Device Tree for V2P-CA15 core tile (TC1 variant) ARM: vexpress: Add Device Tree for V2P-CA9 core tile ARM: vexpress: Add Device Tree for V2P-CA5s core tile ARM: vexpress: Motherboard RS1 memory map support ARM: vexpress: Add Device Tree support ARM: vexpress: Use FDT data in platform SMP calls ARM: versatile: Map local timers using Device Tree when possible ARM: vexpress: Get rid of MMIO_P2V This adds full device tree boot support for the versatile express platform, as has been awaited for a long time. Conflicts: arch/arm/mach-vexpress/core.h The definition of AMBA_DEVICE was removed in one branch, and the definition of MMIO_P2V was removed in the other branch.
