It has three QCN9274 WiFi devices connected to PCIe1, PCIe2, and PCIe3. These devices are also connected among themselves via WSI connection. This WSI connection is essential to exchange control information among these devices The WSI connection in RDP433 is represented below: +-------+ +-------+ +-------+ | pcie1 | | pcie2 | | pcie3 | | | | | | | +----->| wsi |------->| wsi |------->| wsi |-----+ | | grp 0 | | grp 0 | | grp 0 | | | +-------+ +-------+ +-------+ | +------------------------------------------------------+ Based on the above, the wifi node properties for QCN9274 at pcie2 are (considering QCN9274 at pcie2 is WSI controller): - qcom,wsi-controller - ports: tx-port (port@0): endpoint at pcie3 RX port. rx-port (port@1): endpoint at pcie1 TX port. Hence, add WiFi nodes with WSI properties for all three QCN9274 devices connected to RDP433.
