		* 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>;
		};
