Re: [PATCH v2 4/4] PCI: of: introduce of_pci_verify_node()

[sashiko-bot@kernel.org]

> Commit 407d1a51921e9 ("PCI: Create device tree node for bridge") linked
> the PCI enumeration process together with devicetree, creating a devicetree
> node for discovered PCI bridges.  Its successor commit ae9813db1dc5a ("PCI:
> Add quirks to generate device tree node for Xilinx Alveo U50") shows how
> to use a PCI final fixup quirk to also create a devicetree node for a
> non-bridge PCI device.  These changes allowed devicetree overlays to
> describe components downstream of a PCI device, by providing a place to
> attach the overlay.

> Note that the dynamic devicetree node is only created if the device didn't

> Later, commit aa7b4bbcb3a1d ("arm64: dts: qcom: qcs6490-rb3gen2: Add
> TC9563 PCIe switch node") *pre-defined* devicetree nodes to represent the
> PCI device nodes that would (also) be discovered via the PCI enumeration
> [ ... ]
