Subject[PATCH v2] ARM: dts: odroidxu3: Enable wake alarm of S2MPS11 RTC
Date
The IRQB of S2MPS11 PMIC is wired to XEINT4 (GPX0-4) through pull-up
resistor.

Add interrupt properties and pinctrl configuration to enable RTC wake
alarm of rtc-s5m driver. This also removes a warning:
sec_pmic 4-0066: No interrupt specified, no interrupts

Changes since v1:
1. Choose proper pinctrl node for gpx0-4: this should be pinctrl_0, not
pinctrl_1.
2. Add Javier's reviewed-by.
