PATCH v2 1/1 ARM: exynos: Bring back reboot on Exynos5410
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.

Eh, I pointed in my last reply what you need to do:
Just add this tag and resend. This is the way of backporting to stable.
Best regards,
Krzysztof
