If we need to manually extend the schema like this it should probably be done for all the CODEC devices.

Several files already do it: git grep name-prefix.yaml The trouble for me would be here to identify which devices qualify from bindings/sound.... everything having #sound-dai-cells?

Pretty much anything could potentially do it, it's a system level thing for when the same device gets instantiated multiple times. It's most relevant when something creates user visible controls.

For multiple speakers attached, it's useful to give them some name. Sound core already supports this, so reference name-prefix.yaml.
