Merge tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM soc board specific updates from Olof Johansson:
"Misc board updates:
- Greg added a handful of boards to KS8695 (since he has stepped up
to maintain it).
- Qualcomm has added DT-only board support for a couple of their
newer SoCs.
- misc other updates for Samsung and Freescale boards."
Fix up trivial conflict in arch/arm/mach-shmobile/board-armadillo800eva.c
due to gpio device data being added next to hdmi device data that got moved.
