Perhaps dai-common.yaml. I'm sure there is some prior art here to consider as well. Rob

But there's no use of similar property on the codec nodes. https://elixir.bootlin.com/linux/latest/source/sound/soc/soc-component.c#L288 /** * snd_soc_component_get_jack_type * @component: COMPONENTs * * Returns the jack type of the component * This can either be the supported type or one read from * devicetree with the property: jack-type. */ This is part of a component, so maybe in sound/component-common.yaml ?
