We have been looking for a way to document that the corresponding DP
port is represented by the USB connector on the device.
Consequently, I believe the best way to document it, would be to use
DisplayPort / USB, when there is no dongle connected, switching to
DisplayPort / HDMI, DisplayPort / VGA, DisplayPort / DisplayPort, etc.
when the actual dongle / display is connected and then switching back to
the DisplayPort / USB when it gets disconnected.
If this sounds good to all parties, I'll post v2, adding this
explanation to the cover letter.
But how can user-space discover that the port is USB-C when it's
connected? That information is lost at this point.
Yes, unfortunately.
(In addition, this clashes with the existing semantics of the
subconnector prop as discussed before: USB-C is not sub-, it's super-.)
Ok. How do we proceed then? Is it fine to add another property for DP
case? Do you have any particular property name in mind? I will follow
with addition of this property then.
