ARM: dts: Add power and lid GPIO keys pinctrl for exynos5250-snow
The Exynos5250 Snow Chromebook has GPIO keys for power and lid so the SoC I/O pins have to be configured in external interrupt mode. Currently, this is working without setting the pinctrl lines but is better to set it explicitly instead of relying on the previous state of the I/O pins. The DTS snippets were taken from the downstream ChromeOS tree. Signed-off-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk> Signed-off-by: Kukjin Kim <kgene@kernel.org>
