I did not pay enough attention to audio-graph-port property which is in
fact supported and could be added as well. Thus the es8311.yaml would be
identical to es8316.yaml. My guess is that I should just add the
"everest,es8311" compatible string to the existing es8316.yaml even if the
two drivers are separate (like for instance mediatek,mt8186-clock.yaml). Is
this correct?
If that's the case:
* should the evereset,es8316.yaml file be renamed to evereset,es831x.yaml?
* should I also add myself to the maintainers list of that schema?
