This is the way of backporting to stable.

Since 8cfc7fdd33080e30b86d21b1a8c9ad0686427ddc ("ARM: EXYNOS: move restart code into pmu driver") PMU support is required in order for the reboot to work. Unfortunately, there is currently no PMU support for 5410. This patch adds exynos5410-pmu to the list of recognized devices. It is okay for the code to have empty struct exynos_pmu_data, in this case only minimal support is enabled. This is enough for SWRESET to work.
