From 6f41a9589e5c8ba597ad7bb0be21e6bf4696b50d Mon Sep 17 00:00:00 2001 From: Yadwinder Singh Brar Date: Sat, 9 May 2015 02:24:25 +0900 Subject: [PATCH] ARM: dts: Add missing irq pinctrl for max77686 on smdk5250 This patch adds pinctrl configuration for using configuring gpx3-2 as an external interrupt from max77686. Though max77686 RTC is enabled and gets probed by default, it doesnt work as its unable to get interrupt. This patch makes max77686 RTC work and also configures it as wakeup source.
