[PATCH 3/5] arm64: dts: qcom: lemans-evk-ifp-mezzanine: use pci for device nodes

[Alex Elder]

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@")
