[PATCH v2 07/20] dt-bindings:iio:adc:nuvoton,nau7802 yaml conversion

Jonathan Cameron

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

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>;
-};
