Sorry, this does not work. Change voltage to 1111111 and check the results.

Actually it's worst ! I've removed the required property (vaud28-supply) but the dt check pass.
Same behavior for some other docs like mt6359.yaml

The at24.yaml doc works as expected, then I tried compare an find the issue, without success...

I've replaced "codec" by "audio-codec", according to [1].
I've tried multiple manner to implement the example code, without success. I'm wondering if what I try to do is the correct way or parse-able by the dt_check.

If I drop this file and implement all these new properties into the MFD PMIC documentation directly, I've the expected dt_check result (function to good or wrong parameters)

Is the implementation above looks good for you ?
