+Atmel AT91RM9200 Real Time Clock
+
+Required properties:
+- compatible: should be: "atmel,at91rm9200-rtc"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- interrupts: rtc alarm/event interrupt
+
+Example:
+
+rtc@fffffe00 {
+ compatible = "atmel,at91rm9200-rtc";
+ reg = <0xfffffe00 0x100>;
+ interrupts = <1 4 7>;
