Missing chassis-type

Sorry, not sure what you mean here... Do you mean like QRD, HDK, MTP, etc.?
If so, then IDP is the chassis type.

Do these pipe clocks not come from QMPPHY?

Yes they do; I just don't have those phys ready yet. I can put a TODO here to
move them if necessary.

Just use <0> instead of adding a dummy fixed clock.
