Unfortunately, I don't quite agree with any of your three solutions. I
still do believe the root problem is that pdev->dev.of_node should be
NULL for the PCIe endpoints, since those devices are not probed with
the Device Tree.

Looking more at this, the pdev->dev.of_node is in fact NULL, but the
code uses the of_node of the parent PCI device.

So in fact the problem is indeed that the subnodes pcie0,0 and pcie1,0
are seen as corresponding to the PCI-to-PCI bridges.

I would suggest changing the interrupt-mask to match any bus number. (Don't
forget that the secondary bus number of each of your emulated bridges will
vary depending on how many devices are detected underneath each root port,
assuming you don't try and partition bus numbers or use domains between ports).

Thanks,
