From e5e5c6d14e39236485bdc706b918486511817678 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Thu, 15 Jan 2015 00:30:35 +0900 Subject: [PATCH] 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.
