You can't remove the property. This is now a warning in linux-next:

Documentation/devicetree/bindings/sound/nxp,tfa989x.example.dt.yaml:
audio-codec@34: 'sound-name-prefix' does not match any of the regexes:
'pinctrl-[0-9]+'
 From schema: /builds/robherring/linux-dt/Documentation/devicetree/bindings/sound/nxp,tfa989x.yaml
Documentation/devicetree/bindings/sound/nxp,tfa989x.example.dt.yaml:
audio-codec@36: 'sound-name-prefix' does not match any of the regexes:
'pinctrl-[0-9]+'
 From schema: /builds/robherring/linux-dt/Documentation/devicetree/bindings/sound/nxp,tfa989x.yaml


Just 'sound-name-prefix: true' is fine

Here too, but I guess we don't have any example to throw a warning?
