CS42L51 audio CODEC
|
|
|
|
Required properties:
|
|
|
|
- compatible : "cirrus,cs42l51"
|
|
|
|
- reg : the I2C address of the device for I2C.
|
|
|
|
Optional properties:
|
|
- VL-supply, VD-supply, VA-supply, VAHP-supply: power supplies for the device,
|
|
as covered in Documentation/devicetree/bindings/regulator/regulator.txt.
|
|
|
|
- reset-gpios : GPIO specification for the reset pin. If specified, it will be
|
|
deasserted before starting the communication with the codec.
|
|
|
|
- clocks : a list of phandles + clock-specifiers, one for each entry in
|
|
clock-names
|
|
|
|
- clock-names : must contain "MCLK"
|
|
|
|
Example:
|
|
|
|
cs42l51: cs42l51@4a {
|
|
compatible = "cirrus,cs42l51";
|
|
reg = <0x4a>;
|
|
clocks = <&mclk_prov>;
|
|
clock-names = "MCLK";
|
|
VL-supply = <®_audio>;
|
|
VD-supply = <®_audio>;
|
|
VA-supply = <®_audio>;
|
|
VAHP-supply = <®_audio>;
|
|
reset-gpios = <&gpiog 9 GPIO_ACTIVE_LOW>;
|
|
};
