I don't seem to have this node, did I loose a patch somewhere?

I rebased my branch on top of Abel's work/next branches for x1e80100,
assuming he sent the USB display port. Apparently this is not the case,
so this makes little sense now. Sorry for the noise, I will come back
once Abel's work get posted or merged.

Best regards,
Krzysztof

Looks sane. Are any UCM changes necessary?

Yes. I already sent topology pull request. For UCM I will send something
soon.

Best regards,
