dt-bindings:iio:adc:nuvoton,nau7802 yaml conversion 



A simple conversion from txt file to yaml.  I added the #io-channel-cells
property as optional to allow the channels of this ADCs to be used
to provide services to other drivers, for example if an analog
accelerometer is connected.

* 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>;

};
