* 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>;
};
