[PATCH v2 1/3] arm64: dts: qcom: monaco: Add compatible to the PCIe Root Port

From: Wei Deng

Date: Tue Jul 28 2026 - 22:42:11 EST


Add 'compatible = "pciclass,0604"' to the pcieport0 node in monaco.dtsi
to allow the PCI subsystem to associate the DT node with the PCI-to-PCI
bridge device. This is required for downstream DT nodes (such as M.2
connectors described as graph endpoints of the Root Port) to be matched
to PCI devices.
