-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>;
-};
