Wait, there is already binding for this device: qcom,wsa881x.yaml. This has to be there, it's the same device, exactly the same. Best regards, Krzysztof

Add binding document for WSA881X family of smart speaker amplifiers that set to work in analog mode only and configurable via i2c only. Such devices are found in Qualcomm QRB4210 RB2 boards with SM4250/SM6115 SoCs.
