Why are we adding a separate DT node with no content for this? This is a single chip, we already know that the CODEC part is there from the DT telling us that the chip is there and what we decide is part of the CODEC is going to depend on what the OS running on the system is doing.
While it looks empty in the DT binding file, it's actually not empty once some standard properties are added to support audio-graph-card.
This tells me you're missing something in the binding defining the DAIs and...
A real world example looks like this:
&cpcap { audio-codec { compatible = "motorola,cpcap-audio-codec"; #sound-dai-cells = <1>;
...that still doesn't require a compatible here.
