But now, I am wondering again about these `empty`codecs:
- in a DT context, should we continue to add / modify such codecs?

We still want to be able to have users just name the CODEC on their board rather than have to type in all the details from the datasheet, if we're going to try to amalgamate the drivers it should still let people do that.
OK. But it seems to me that the codec is not tied to the board, but rather to the audio connector / transmitter.
In the case of the tda998x HDMI transmitter, either i2s or s/pdif may be used, thanks to the actual codecs 'hdmi' and 'spdif tx'. But they don't work the same way: the 'hdmi' codec handles both playback and record, and recording is disabled by program in the sound device, while the 'spdif tx' codec is selected by the codec-dai-name ("dit-hifi" - it is "dir-hifi" for recording). It would be nice if these codecs would have the same behaviour...
