+* Qualcomm Technologies APQ8096 ASoC sound card driver
+
+This binding describes the APQ8096 sound card, which uses qdsp for audio.
+
+- compatible:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must be "qcom,apq8096-sndcard"
+
+- qcom,audio-routing:
+ Usage: Optional
+ Value type: <stringlist>
+ Definition: A list of the connections between audio components.
+ Each entry is a pair of strings, the first being the
+ connection's sink, the second being the connection's
+ source. Valid names could be power supplies, MicBias
+ of codec and the jacks on the board:
Please list out valid values here.
I can list the values for the HDMI playback use-case, but the list would
grow as we start adding wcd9335 codec support.
+
+= dailinks
+Each subnode of sndcard represents either a dailink, and subnodes of each
+dailinks would be cpu/codec/platform dais.
+
+- link-name:
Not a standard property, but I guess that sneaked in with the 8016
binding...
Yes, I followed 8016 bindings.
Am happy to prefix this with qcom if that makes more sense.
+ Usage: required
+ Value type: <string>
+ Definition: User friendly name for dai link
+
+= CPU, PLATFORM, CODEC dais subnodes
+- cpu:
+ Usage: required
+ Value type: <subnode>
+ Definition: cpu dai sub-node
+
+- codec:
+ Usage: Optional
+ Value type: <subnode>
+ Definition: codec dai sub-node
+
+- platform:
+ Usage: Optional
+ Value type: <subnode>
+ Definition: platform dai sub-node

+- sound-dai:
+ Usage: required
+ Value type: <phandle>
phandle with args.
Yep.
