* 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:
Valid names include:
Board Connectors:
"Headphone Left"
"Headphone Right"
"Earphone"
"Line Out1"
"Line Out2"
"Line Out3"
"Line Out4"
"Analog Mic1"
"Analog Mic2"
"Analog Mic3"
"Analog Mic4"
"Analog Mic5"
"Analog Mic6"
"Digital Mic2"
"Digital Mic3"
Audio pins and MicBias on WCD9335 Codec:
"MIC_BIAS1
"MIC_BIAS2"
"MIC_BIAS3"
"MIC_BIAS4"
"AMIC1"
"AMIC2"
"AMIC3"
"AMIC4"
"AMIC5"
"AMIC6"
"AMIC6"
"DMIC1"
"DMIC2"
"DMIC3"
= 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>
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 with arguments>
Definition: dai phandle/s and port of CPU/CODEC/PLATFORM node.
Example:
audio {
compatible = "qcom,apq8096-sndcard";
qcom,model = "DB820c";
mm1-dai-link {
link-name = "MultiMedia1";
cpu {
sound-dai = <&q6asmdai MSM_FRONTEND_DAI_MULTIMEDIA1>;
};
};
hdmi-dai-link {
link-name = "HDMI Playback";
cpu {
sound-dai = <&q6afe HDMI_RX>;
};
platform {
sound-dai = <&q6adm>;
};
codec {
sound-dai = <&hdmi 0>;
};
};
};
