Merge branch 'samsung/cleanup' into next/boards
Conflicts:
arch/arm/mach-imx/mach-imx6q.c
arch/arm/mach-omap2/board-ti8168evm.c
arch/arm/mach-s3c64xx/Kconfig
arch/arm/mach-tegra/Makefile
arch/arm/mach-tegra/board-dt-tegra20.c
arch/arm/mach-tegra/common.c
Lots of relatively simple conflicts between the board
changes and stuff from the arm tree. This pulls in
the resolution from the samsung/cleanup tree, so we
don't get conflicting merges.
