+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.
