NXP LPC1850 DAC bindings
Required properties:
- compatible: Should be "nxp,lpc1850-dac"
- 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:
dac: dac@400e1000 {
compatible = "nxp,lpc1850-dac";
reg = <0x400e1000 0x1000>;
interrupts = <0>;
clocks = <&ccu1 CLK_APB3_DAC>;
vref-supply = <&reg_vdda>;
resets = <&rgu 42>;
status = "disabled";
};
