1* NXP LPC32xx SoC ADC controller 2 3Required 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 9Optional: 10 - vref-supply: The regulator supply ADC reference voltage, optional 11 for legacy reason, but highly encouraging to us in new device tree 12 13Example: 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 }; 22
