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 = <&reg_audio>;

	VD-supply = <&reg_audio>;

	VA-supply = <&reg_audio>;

	VAHP-supply = <&reg_audio>;

	reset-gpios = <&gpiog 9 GPIO_ACTIVE_LOW>;
