-Audio Graph Card:
-
-Audio Graph Card specifies audio DAI connections of SoC <-> codec.
-It is based on common bindings for device graphs.
-see ${LINUX}/Documentation/devicetree/bindings/graph.txt
-
-Basically, Audio Graph Card property is same as Simple Card.
-see ${LINUX}/Documentation/devicetree/bindings/sound/simple-card.yaml
-
-Below are same as Simple-Card.
