Do not need '|' unless you need to preserve formatting.

Did you update the PMIC wrapper binding with ref to this?

You did not test the DTS.

I think I raised the issue already: please make necessary fixes to the
binding (with explanation) or to the DTS, when converting the binding.

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation

Definitely no underscores. Probably this is "codec" or "audio-codec".
