+* 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>;
+ };
