WSI stands for WLAN Serial Interface. It is used for the exchange of specific control information across radios based on the doorbell mechanism. This WSI connection is essential to exchange control information among these devices Hence, describe WSI interface supported in QCN9274 with the following properties: - qcom,wsi-group-id: It represents the identifier assigned to the WSI connection. All the ath12k devices connected to same WSI connection have the same wsi-group-id. - qcom,wsi-index: It represents the identifier assigned to ath12k device in the order of the WSI connection. - qcom,wsi-num-devices: Number of devices connected through WSI in the same group ID.
