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>;
};
