  1 +* NXP LPC32xx SoC Real Time Clock controller
  2 +
  3 +Required properties:
  4 +- compatible: must be "nxp,lpc3220-rtc"
  5 +- reg: physical base address of the controller and length of memory mapped
  6 + region.
  7 +- interrupts: The RTC interrupt
  8 +
  9 +Example:
  10 +
  11 + rtc@40024000 {
  12 + compatible = "nxp,lpc3220-rtc";
  13 + reg = <0x40024000 0x1000>;
  14 + interrupts = <52 0>;
  15 + };
