This commit brings exynos4-dt in line with recent changes to mach-exynos tree, specifically: - Fixes build break related to replacing plat/exynos4.h with common.h in commitcc511b8d84("ARM: 7257/1: EXYNOS: introduce arch/arm/mach-exynos/common.[ch]") - Converts machine to use CONFIG_MULTI_IRQ_HANDLER as done for other machines in commit4e44d2cb95("ARM: exynos4: convert to CONFIG_MULTI_IRQ_HANDLER") - Adds restart specifier as done for other machines in commit9eb4859564("ARM: 7262/1: restart: EXYNOS: use new restart hook") Signed-off-by: Karol Lewandowski <k.lewandowsk@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Cc: Thomas Abraham <thomas.abraham@linaro.org> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

|
|
* For drivers that require platform data to be provided from the machine

|
* supplied. But it should be noted that this is a temporary mechanism and
