WSA883x Soundwire slave device as child of Soundwire master in Bolero codec
Required properties:
- compatible = "qcom,wsa883x";
- reg: Specifies the WSA883x soundwire slave unique device address
- qcom,spkr-sd-n-gpio: speaker reset gpio
Optional properties:
- bolero-handle: phandle to bolero codec
- cdc-vdd-1p8-supply: phandle of VDD 1.8V supply's regulator device tree node.
- qcom,cdc-vdd-1p8-voltage: VDD 1.8V supply's voltage level min and max in mV.
- qcom,cdc-vdd-1p8-current: VDD 1.8V supply's max current in mA.
- qcom,cdc-static-supplies: List of supplies to be enabled prior to codec
hardware probe. Supplies in this list will be
stay enabled.
Example:
wsa883x_0221: wsa883x@02170221 {
compatible = "qcom,wsa883x";
reg = <0x02 0x02170221>;
qcom,spkr-sd-n-gpio = <&tlmm 80 0>;
bolero-handle = <&bolero>;
cdc-vdd-1p8-supply = <&S10B>;
qcom,cdc-vdd-1p8-voltage = <1800000 1800000>;
qcom,cdc-vdd-1p8-current = <20000>;
qcom,cdc-static-supplies = "cdc-vdd-1p8";
