The module is interfaced via LGA and is compatible with the M.2 Key E. Add wireless-lga-connector node using pcie-m2-e-connector binding, connecting PCIe port 0 to the WiFi interface and UART10 port 3 to the Bluetooth interface. Add pcie@1,0 downstream port node with pciclass,0604 compatible so the pci-pwrctrl driver can acquire the power sequencer and enable the M.2 slot before PCIe enumeration. Add nfa725b_default_state pinctrl for the W_DISABLE1/2 GPIOs (gpio56/gpio55) used by the power sequencer.
