Introduce the 'widgets' property, allowing the creation of widgets from
4 template widgets: Microphone, Line, Headphone, and Speaker. Also
introduce the 'hp-det-gpios' property, which allows using headphone
detection using the specified GPIO.

why not direct ref Documentation/devicetree/bindings/sound/audio-graph.yaml
and define these again here.

We don't actually want all the properties from 'audio-graph.yaml' (for the moment at least). Also ref-ing 'audio-graph.yaml' will make the 'dais' property required, which is not targeted in this patch. Maybe Kuninori Morimoto can comment more on this.

I'm not a DT yaml expert, but audio-graph.yaml is for audio-graph-card and
its custom card. unfortunately audio-graph-card2 is using different style,
so ref audio-graph.yaml on audio-graph-card2 is impossible, or makes yaml
more complex.

Thank you for your help !!
