While working on upstream support for the Toshiba TC9564 SoC I
discovered that the way its PCIe endpoint function nodes are
defined in devicetree files is incorrect. Two issues have been
pointed out during the course of review:
- Only PCI bridge device nodes should contain this property:
device_type = "pci";
- Only bridge device nodes should be named "pcie@" (or "pci@")
The second of these was previously addressed by this series:
https://lore.kernel.org/lkml/20260901172058.1512508-1-elder@riscstar.com/
Instead, those changes are now included here.
These errors existed for the RB3gen2 platform, but five other Qualcomm
devicetree files had this same mistake (all describing a TC9564 SoC).
This series removes the device_type property where it is defined
for a PCI endpoint function, and renames such nodes "dev@".
The #address-cells, #size-cells, and ranges properties are also
removed for these nodes. These will be restored when they are
known to be needed (to implement pci-ep-bus sub-nodes).

Between version 2 and version 3:
- Added Reviewed-by from Abel (and for the last patch, Mani)
- Renamed all nodes "dev@" rather than "pcie@" or "pci@"
Version 2 is available here:
https://lore.kernel.org/lkml/20260901013654.1343537-1-elder@riscstar.com/
Between version 1 and version 2:
- Added Reviewed-by from Mani and Konrad
- Added a patch that updates "qcs8550-rb5gen2.dts" as well
Version 1 is available here:
https://lore.kernel.org/lkml/20260807195846.456079-1-elder@riscstar.com/
