+NXP LPC1850 ADC bindings
+
+Required properties:
+- compatible: Should be "nxp,lpc1850-adc"
+- reg: Offset and length of the register set for the ADC device
+- interrupts: The interrupt number for the ADC device
+- clocks: The root clock of the ADC controller
+- vref-supply: The regulator supply ADC reference voltage
+- resets: phandle to reset controller and line specifier
+
+Example:
+
+adc0: adc@400e3000 {
+       compatible = "nxp,lpc1850-adc";
+       reg = <0x400e3000 0x1000>;
+       interrupts = <17>;
+       clocks = <&ccu1 CLK_APB3_ADC0>;
+       vref-supply = <&reg_vdda>;
+       resets = <&rgu 40>;
+       status = "disabled";
+};
