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";
};
