Although, would dual link be a I don't like inferring the information. With the above, you can't find out that the DVI connector has digital and analog support before all the drivers are loaded. > 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. > The port node seems a bit pointless. There's another thread discussing the ports and endpoints. The port node represents, for example, the pins for the connection for that device. And an endpoint-endpoint link represents wires between two ports.
