Atmel AT91RM9200 Real Time Clock



Required properties:

- compatible: should be: "atmel,at91rm9200-rtc", "atmel,at91sam9x5-rtc" or

  "microchip,sam9x60-rtc"

- reg: physical base address of the controller and length of memory mapped

  region.

- interrupts: rtc alarm/event interrupt

- clocks: phandle to input clock.



Example:



rtc@fffffe00 {

	compatible = "atmel,at91rm9200-rtc";

	reg = <0xfffffe00 0x100>;

	interrupts = <1 4 7>;

	clocks = <&clk32k>;

};
