+This binding describes the APQ8096 sound card, which uses qdsp for audio.

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.
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.
