No SBU? Please at least document, which ports have DP support by adding
the SBU nodes and a comment why the DP is not wired up (e.g. lack of the
retimer driver).

Thundercomm, not THUNDERCOMM. Also, which devkit? does it have some
name? Usually there is a model or a codename for a device.

How does it match the data-role = "dual" set for connector@0? What does
UCSI report for all the ports?
