Merge branch 'samsung/defconfig' into next/defconfig
From Kukjin Kim <kgene.kim@samsung.com>: It is including new exynos_defconfig for DT configuration of exynos4 and exynos5 together. The old exynos4_defconfig will be used for non-DT for a while and we will try to move on using exynos_defconfig for only DT. * samsung/defconfig: ARM: exynos_defconfig: enable more platforms in defconfig Signed-off-by: Arnd Bergmann <arnd@arndb.de>
