I don't particularly like that - that makes the assumption that AP0 always means I2S. What if a future chip decides to allow SPDIF on AP0? Why should we need to re-invent the binding?

IMHO, it would be much better to make this explicit.

OK.

Note that the "video-ports" and "audio-ports" are just labels in the DT file; they aren't carried through to the resulting DT binary file, so they don't have any meaning to the kernel.

Right, so, either the port type must be explicitly defined, or the name of the property giving the port value also gives the port type (nxp,video-port / nxp,audio-port).
