Hi Laurent,
Sorry for I don't see the interest:
- it is obvious that the HDMI connector is a 'hdmi-connector'!
- the physical connector type may be changed on any board by a soldering
iron or a connector to connector cable.
- what does the software do with the connector type?
- why not to put the connector information in the HDMI device?
And, if I follow you, the graph of ports could also be used to describe
the way the various parts of the SoCs are powered, to describe the pin
connections, to describe the USB connectors, to describe the board
internal hubs and bridges...
