Hmm, well endpoints for a single port are exclusive. So it's either a
single port and a single endpoint, or two ports and two endpoints. I
think dual link has to be single port & endpoint, as the TMDS links need
to be driven together as a single bus.

And dual-link is not really "two links". DVI dual-link means 1 clock
lane and 6 data lanes, compared to 1 clock lane and 3 data lanes for
single-link.

What about having a property for the number of data lanes?
