    description:
      If present, the LRCM bit of R24 (Additional control 2) gets set,
      indicating that ADCLRC and DACLRC pins will be disabled only when ADC
      (Left and Right) and DAC (Left and Right) are disabled.
      When WM8960 works on synchronize mode and DACLRC pin is used to supply
      frame clock, it will no frame clock for captrue unless enable DAC to
      enable DACLRC pin. If shared-lrclk is present, no need to enable DAC for
      captrue.
