Subject: [RFC PATCH v2 5/5] arm64: dts: qcom: ipq9574: Add WiFi nodes for RDP433
The RDP433 is a Qualcomm Reference Design Platform based on the
IPQ9574. 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:
+-------+ +-------+ +-------+
| pcie2 | | pcie3 | | pcie1 |
| | | | | |
+----->| wsi |------->| wsi |------->| wsi |-----+
| | grp 0 | | grp 0 | | grp 0 | |
| +-------+ +-------+ +-------+ |
+------------------------------------------------------+
Based on the above, the WSI properties for QCN9274 at pcie2 are
(considering QCN9274 at pcie2 is WSI master):
qcom,wsi-group-id = 0
qcom,wsi-master
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.
