[PATCH v2 06/13] arm64: dts: qcom: lemans-evk: Enable PCIe support

From: Wasim Nazir
Date: Wed Sep 03 2025 - 07:50:25 EST


From: Sushrut Shree Trivedi <quic_sushruts@xxxxxxxxxxx>

Enable PCIe0 and PCIe1 along with the respective phy-nodes.

PCIe0 is routed to an m.2 E key connector on the mainboard for wifi
attaches while PCIe1 routes to a standard PCIe x4 expansion slot.
