single endpoint or 2 endpoints? How would you differentiate that?
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?
That was already suggested by Philipp in this thread. I don't see anything wrong with that, but I don't really see benefit either. "dual-link" is a standard term for 6 data lanes for the DVI connector. And the choices are 3 or 6 data lanes, nothing else.
The number of lanes of a DisplayPort connector could be 1 to 4. Also, there's dual-mode DP which can use four lanes to drive somewhat-like-HDMI single link TMDS signals.
