+MT63xx is Mediatek PMIC chip series. RTC is one submodule of PMIC chip.
+The RTC maintains seconds counter, also provide alarm function.

+Required properties:
+- compatible: Should be "mediatek,mt6397-rtc".
+- reg: base physical address and size of the registers.
+- interrupt-parent: phandle for the interrupt controller
+- interrupts: RTC alarm interrupt.
+
+Examples:
+rtc: rtc at e000 {
+ compatible = "mediatek,mt6397-rtc";
+ reg = <0xe000 0x3e>;
+ interrupt-parent = <&pmic>;
+ interrupts = <20 IRQ_TYPE_LEVEL_HIGH>;
