description:
  Qualcomm WCD9378 (Tambora) SoundWire codec. The same silicon can be
  fused for a mobile (non-SDCA) mode or an SDCA-compliant mode; the
  qcom,sdca-compliant property selects the latter and is required by
  this driver.

  qcom,sdca-compliant:
    description:
      Present when the codec is fused as SDCA-compliant. The mobile
      (non-SDCA) variant carries the same class-ID compatible and is
      handled by a different driver.

  qcom,port-mapping:
    description:
      Each entry maps a slave data port to a master data port.
      Entries are in order starting from slave port 1; slave port 0
      is reserved and not represented. SDCA-compliant mode uses 8
      entries covering DP1..DP8.
