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.
