Subject: [PATCH 3/5] arm64: dts: qcom: lemans-evk-ifp-mezzanine: use pci for device nodes
Date: Tue, 1 Sep 2026 12:20:55 -0500 [thread overview]
Message-ID: <20260901172058.1512508-4-elder@riscstar.com> (raw)
In-Reply-To: <20260901172058.1512508-1-elder@riscstar.com>
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 Lemans EVK IFP mezzanine has a TC9564 SoC, which 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@").
Unfortunately, of_node_is_pcie() causes nodes named "pcie@" to be
treated as PCI bridges, which PCI endpoints are not. The previous
name "pci" matched such nodes as "default-flags" bus type, defined
in the of_busses[] array.
Rename the PCIe endpoint nodes "pci@" so they are not mistaken for
bridge nodes by the devicetree parsing code. This restores the
previous behavior, and allows them to be used for PCI endpoint bus.
Fixes: e806c63ba51a7 ("arm64: dts: qcom: Rename pci@ nodes to pcie@")
