Add support for the M.2 Key-E QCC2072 wireless solution on the Talos
Lyra EVK. The M.2 Key-E slot is connected via the QPS615 PCIe
switch (TC9563) PCIe1 Downstream port for WiFi, and via SoC UART7
(GPIO10-13) for Bluetooth.
- talos-lyra-som.dtsi: Add compatible = "pciclass,0604" and OF graph
endpoint (tc9563_pcie1_ep) to the QPS615 PCIe1 Downstream port
(pcie@1,0) to allow PCI subsystem DT node matching for pwrseq
- talos-lyra-evk.dts:
- Add GPIO-controlled vreg_keye_3p3 regulator via expander3 GPIO6
- Add expander3 (TCA9538 at 0x3c) for M.2 Key-E slot power control
- Add wifi-bt-connector (pcie-m2-e-connector) with vpcie3v3-supply,
w-disable1 (GPIO51) for WiFi and w-disable2 (GPIO85) for BT
- Wire endpoint cross-references via &tc9563_pcie1_ep and &uart7_ep
