Change voltage to 1111111 and check the results. Best regards, Krzysztof

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've removed the required property (vaud28-supply) but the dt check pass. > Same behavior for some other docs like mt6359.yaml Yeah, the schema is not applied. There is nothing selecting it, so this is no-op schema. I don't know what exactly you want to describe, but usually either you miss compatible or this should be just part of parent node. > > 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.

Add MT8365 audio codec bindings to set required and optional voltage properties between the codec and the board. The properties are: - phandle of the requiered power supply. - Setup of microphone bias voltage. - Setup of the speaker pin pull-down.
