CS42448/CS42888 audio CODEC



Required properties:



  - compatible : must contain one of "cirrus,cs42448" and "cirrus,cs42888"



  - reg : the I2C address of the device for I2C



  - clocks : a list of phandles + clock-specifiers, one for each entry in

    clock-names



  - clock-names : must contain "mclk"



  - VA-supply, VD-supply, VLS-supply, VLC-supply: power supplies for the device,

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



Optional properties:



  - reset-gpios : a GPIO spec to define which pin is connected to the chip's

    !RESET pin



Example:



cs42888: codec@48 {

	compatible = "cirrus,cs42888";

	reg = <0x48>;

	clocks = <&codec_mclk 0>;

	clock-names = "mclk";

	VA-supply = <&reg_audio>;

	VD-supply = <&reg_audio>;

	VLS-supply = <&reg_audio>;

	VLC-supply = <&reg_audio>;

	reset-gpios = <&pca9557_b 1 GPIO_ACTIVE_LOW>;
