[PATCH v4 2/5] arm64: dts: qcom: x1e80100: add bus topology for PCIe domain 3

From: Wenbin Yao
Date: Wed Jun 04 2025 - 04:07:20 EST


From: Qiang Yu <qiang.yu@xxxxxxxxxxxxxxxx>

Add pcie3_port node to represent the PCIe bridge of PCIe3 so that PCI slot
voltage rails can be described under this node in the board's dts.
