Having someone to discuss problems and to give some answers or hints
from the datasheet has been very helpful. So also thanks to you :-)

I do have a few patches sitting in my tree which add the necessary
bits for the Lantiq SoCs to the
drivers/pci/controller/dwc/pcie-intel-gw.c driver (which is upstream
since Linux 5.6)
unfortunately this requires some extra work, including changes to the
PCI driver (which needs to move away from the MIPS specific PCI bits
and over to the "generic" PCI subsystem)
That said, working on that is going to be easier when we have Linux
5.10 support (even if it's just the testing kernel version)

Best regards,
