56      indicating that ADCLRC and DACLRC pins will be disabled only when ADC
57      (Left and Right) and DAC (Left and Right) are disabled.
58      When WM8960 works on synchronize mode and DACLRC pin is used to supply
59      frame clock, it will no frame clock for captrue unless enable DAC to
60      enable DACLRC pin. If shared-lrclk is present, no need to enable DAC for
61      captrue.
