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>;
};
