   1 * NXP LPC32xx SoC ADC controller
   2
   3 Required properties:
   4 - compatible: must be "nxp,lpc3220-adc"
   5 - reg: physical base address of the controller and length of memory mapped
   6   region.
   7 - interrupts: The ADC interrupt
   8
   9 Optional:
  10  - vref-supply: The regulator supply ADC reference voltage, optional
  11    for legacy reason, but highly encouraging to us in new device tree
  12
  13 Example:
  14
  15         adc@40048000 {
  16                 compatible = "nxp,lpc3220-adc";
  17                 reg = <0x40048000 0x1000>;
  18                 interrupt-parent = <&mic>;
  19                 interrupts = <39 0>;
  20                 vref-supply = <&vcc>;
  21         };
