CS4349 audio CODEC
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : "cirrus,cs4349"
|
||||
|
||||
- reg : the I2C address of the device for I2C
|
||||
|
||||
Optional properties:
|
||||
|
||||
- reset-gpios : a GPIO spec for the reset pin.
|
||||
|
||||
Example:
|
||||
|
||||
codec: cs4349@48 {
|
||||
compatible = "cirrus,cs4349";
|
||||
reg = <0x48>;
|
||||
reset-gpios = <&gpio 54 0>;
