+RTC controller for the Allwinner A31
+
+Required properties:
+- compatible   : Should be "allwinner,sun6i-a31-rtc"
+- reg          : physical base address of the controller and length of
+                 memory mapped region.
+- interrupts   : IRQ lines for the RTC alarm 0 and alarm 1, in that order.
+
+Example:
+
+rtc: rtc@01f00000 {
+       compatible = "allwinner,sun6i-a31-rtc";
+       reg = <0x01f00000 0x54>;
+       interrupts = <0 40 4>, <0 41 4>;
+};
