Kernel-4.18.0-80.el8_qcom,apq8096

• 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”

• qcom,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"

        "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:
  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.

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>;
    };
};
