* 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"
|
||||
|
||||
- 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:
|
||||
Valid names include:
|
||||
|
||||
Board Connectors:
|
||||
"Headphone Left"
|
||||
"Headphone Right"
|

|
||||
- aux-devs
|
||||
Usage: optional
|
||||
Value type: <array of phandles>
|
||||
Definition: A list of phandles for auxiliary devices (e.g. analog
|
||||
amplifiers) that do not appear directly within the DAI

|
||||
using "audio-routing".
|
||||
|
||||
= dailinks
|
||||
Each subnode of sndcard represents either a dailink, and subnodes of each
|
||||
dailinks would be cpu/codec/platform dais.
|
||||
|
||||
- link-name:
|
||||
Usage: required
|
||||
Value type: <string>
|

Usage: required
|
||||
Value type: <subnode>
|
||||
Definition: cpu dai sub-node
|
