Hi.
Have you tried if danube can simply be compatible with vanilla "snps,dwc2"?
The main reason we created our own definition for lantiq is that arx
and xrx have fifo sizes smaller than what the dwc2 autodetection
mechanism expects.
I remember finding some references in ifxhcd code which would suggest
that danube had bigger fifo and thus would maybe work without any
special treatment.
