* NXP LPC32xx SoC ADC controller



Required properties:

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

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

  region.

- interrupts: The ADC interrupt



Example:



	adc@40048000 {

		compatible = "nxp,lpc3220-adc";

		reg = <0x40048000 0x1000>;

		interrupt-parent = <&mic>;

		interrupts = <39 0>;

	};
