This patch adds cros-ec related device nodes to exynos5250-snow.dts. It also adds a gpio node to exynos5250.dtsi.
Signed-off-by: Hung-ying Tyan tyanh@chromium.org
--- Changes in v5: - Change ec-interrupt gpio pin from 174 to 782. This has to be changed again after the GPIO pin numbering patches (http://patchwork.ozlabs.org/patch/233417) are in.
Changes in v4: - Added commit message.
Changes in v3: None Changes in v2: - Added gpio node to exynos5250.dtsi. - Dropped the period from commit subject.
