* 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>;
};
