* Nuvoton NAU7802 Analog to Digital Converter (ADC)

Required properties:
  - compatible: Should be "nuvoton,nau7802"
  - reg: Should contain the ADC I2C address

Optional properties:
  - nuvoton,vldo: Internal reference voltage in millivolts to be
    configured valid values are between 2400 mV and 4500 mV.
  - interrupts: IRQ line for the ADC. If not used the driver will use
    polling.

Example:
adc2: nau7802@2a {
	compatible = "nuvoton,nau7802";
	reg = <0x2a>;
	nuvoton,vldo = <3000>;
};
