Subject[PATCH] ARM: dts: Move syscon reboot/poweroff to common dtsi for Exynos
Date
All Exynos SoCs have the same syscon reboot and poweroff device nodes so
there is no need to duplicate the same on each SoC dtsi and can be moved
to a common dtsi that can be included by all the SoCs dtsi files.

Hello,

The patch was tested on an Exynos5800 Peach Pi Chromebook and an
Exynos5422 Odroid XU4 board. Reboot and poweroff worked for both.

But testing on Exynos3 and Exynos4 will be highly appreciated.

Best regards,
Javier
