Required properties:
|
|
- compatible : "dioo,dio2125" or "simple-audio-amplifier"
|
|
|
|
Optional properties:
|
|
- enable-gpios : the gpio connected to the enable pin of the simple amplifier
|
|

Example:
|
|
|
|
amp: analog-amplifier {
|
|
compatible = "simple-audio-amplifier";
|
|
VCC-supply = <®ulator>;
|
|
enable-gpios = <&gpio GPIOH_3 0>;
