* Qualcomm Technologies APQ8096 ASoC sound card driver This binding describes the APQ8096 sound card, which uses qdsp for audio. - compatible: Usage: required Value type: Definition: must be "qcom,apq8096-sndcard" - audio-routing: Usage: Optional Value type: 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" - model: Usage: required Value type: Definition: The user-visible name of this sound card. - aux-devs Usage: optional Value type: Definition: A list of phandles for auxiliary devices (e.g. analog amplifiers) that do not appear directly within the DAI links. Should be connected to another audio component 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: Definition: User friendly name for dai link = CPU, PLATFORM, CODEC dais subnodes - cpu: Usage: required Value type: Definition: cpu dai sub-node - codec: Usage: Optional Value type: Definition: codec dai sub-node - platform: Usage: Optional Value type: Definition: platform dai sub-node - sound-dai: Usage: required Value type: Definition: dai phandle/s and port of CPU/CODEC/PLATFORM node. Obsolete: qcom,model: String for soundcard name (Use model instead) qcom,audio-routing: A list of the connections between audio components. (Use audio-routing instead) Example: audio { compatible = "qcom,apq8096-sndcard"; 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>; }; }; };
