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