Subject: [PATCH v4 09/15] ASoC: dt-bindings: audio-graph: Convert bindings to json-schema
Date: Fri, 16 Oct 2020 20:12:56 +0530
Message-ID: <1602859382-19505-10-git-send-email-spujar@nvidia.com> (raw)
In-Reply-To: <1602859382-19505-1-git-send-email-spujar@nvidia.com>

Convert device tree bindings of audio graph card to YAML format. Also
expose some common definitions which can be used by similar graph based
audio sound cards.

-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.
