^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3) Audio Graph Card specifies audio DAI connections of SoC <-> codec.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4) It is based on common bindings for device graphs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) see ${LINUX}/Documentation/devicetree/bindings/graph.txt

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) Basically, Audio Graph Card property is same as Simple Card.
