The MSI Primo81 tablet has a micro HDMI connector at the bottom.
This is connected to the SoCs HDMI output.

Enable the display pipeline and the HDMI output.

Should we add a connector type for this one?

c as in USB Type C? I'd prefer to see a new compatible string. Is type
even documented?

Indeed it is:

Probably as in HDMI Type C (there are Type A, C, and D connectors, aka
"regular", "mini", and "micro").

Correct.
