The reality of the driver is that it makes almost no use of the graph itself, except via drm_of_find_possible_crtcs() to find the connected CRTCs. If it is connected to an I2S source, then it probably needs a port specification for that. If someone wants to describe the HDMI connector (which I don't see any point in) then they likely need a
I can't comment on the point of describing the HDMI connector.
port specification for that too. However, the driver itself doesn't care about any of those.
