ASoC: dt-bindings: Convert Simple Amplifier binding to a schema 



Simple audio amplifiers are supported by Linux with a matching device
tree binding.

Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

Simple Amplifier Audio Driver



Required properties:

- compatible : "dioo,dio2125" or "simple-audio-amplifier"



Optional properties:

- enable-gpios : the gpio connected to the enable pin of the simple amplifier

- VCC-supply   : power supply for the device, as covered

                 in Documentation/devicetree/bindings/regulator/regulator.txt



Example:



amp: analog-amplifier {

	compatible = "simple-audio-amplifier";

	VCC-supply = <&regulator>;

	enable-gpios = <&gpio GPIOH_3 0>;

};
