I believe you will need an "interrupt-map" property here, to map the host interrupts to the INTA-INTD lines of the attached devices.Legacy interrupts are something I cannot test at all because I have no hardware that supports them.
Hmm, I thought all PCIe hardware has to support them when you do not enable MSI. What hardware do you have then?

I'm not sure whether we want to have a device_type="pciex" property here. powerpc and sparc seem to use that information, to distinguish a pcie bus from pci or cardbus.That'd be rather useless information given that the Tegra is unlikely to support either PCI or CardBus at some point.
But the generic code does not know that. Arnd
