Now I have to re-check to see what you really have in mind. Do you think about
creating two different PCIe nodes, one for root-complex and one for endpoint
functionality? Or is your idea to add a property to the existing PCIe
device-tree node (like "mode = endpoint"), or perhaps change the device_type
from "pci" to "pci-endpoint"? I would vote for the latter.
Best regards,
Stefan
