Hi Rob,

>> Add device tree binding properties of generic graph to ASoC component
>> devices. This allows to define audio ports out of these components or
>> DAIs and audio graph based sound card can be realised with this.
> This is all dependent on graph.yaml being applied which hasn't happened
> yet. I guess I'll need to provide a branch as there's multiple
> subsystems needing it.

Since "ASoC: graph card schema rework" series is merged now, referencing 
"audio-graph-port.yaml" should be sufficient here?
