* NXP LPC32xx SoC Real Time Clock controller



Required properties:

- compatible: must be "nxp,lpc3220-rtc"

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

  region.

- interrupts: The RTC interrupt



Example:



	rtc@40024000 {

		compatible = "nxp,lpc3220-rtc";

		reg = <0x40024000 0x1000>;

		interrupts = <52 0>;

	};
