Subject: [PATCH 0/5] arm64: dts: qcom: use pci for device nodes
Date: Tue,  1 Sep 2026 12:20:52 -0500	[thread overview]
Message-ID: <20260901172058.1512508-1-elder@riscstar.com> (raw)

A recent change caused the embedded PCIe endpoints on TC9564 SoCs to
be treated by the devicetree code as PCI buses, which is incorrect.

The TC9564 includes a PCIe switch with one upstream port and two
downstream (external) ports, plus a third downstream port.  The
third port has an embedded PCIe endpoint with two functions, each
providing access to a 10 Gbps capable Ethernet interface.

The devicetree nodes representing these functions were previously
named "pci@" but were renamed in the interest of consistency in
commit e806c63ba51a7 ("arm64: dts: qcom: Rename pci@ nodes to pcie@").

This unfortunately changed the way the devicetree code treats the
nodes, because of_bus_pci_match() considers any node named pcie@
that has no device_type property to be a PCI bus.

The previous name "pci" matched such nodes as "default-flags" bus type
(defined in the of_busses[] array).  This series restores the previous
behavior for these endpoint nodes.
