+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 theconnection's sink, the second being the connection'ssource. Valid names could be power supplies, MicBiasof codec and the jacks on the board:
Please list out valid values here.
+= 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...
- Usage: required
- Value type: <string>
- Definition: User friendly name for dai link
+= CPU, PLATFORM, CODEC dais subnodes +- cpu:
- Usage: required
- Value type: <subnode>
