From: Yadwinder Singh Brar <yadi.brar@xxxxxxxxxxx> 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.
