Why is the vchiq node in the tree twice? For me to even respond anymore
you you going to have to include your entire dtb(whatever you are
using) run through dtc -I dtb -O dts.  You are also going to have to
include your exact .config file you used for building, and exactly what
these DWC2 fixeups are.

You don't even state exactly what platform you are using, Is it even an
RPI of some kind.
