  /* There are two bits of information that the driver needs in order
     to select the correct routing: the operating mode and the selection
     of the Y input (external or internal).
  
     The first two operating modes expect a composite signal on the Y input,
     the second two operating modes use both the Y and C inputs.
  
     Normally YCS_MODE is used for tuner and composite inputs, and the
     YCNR mode is used for S-Video inputs.
  
     The external Y-ADC is selected when the composite input comes from a
     upd64031a ghost reduction device. If this device is not present, or
     the input is a S-Video signal, then the internal Y-ADC input should
     be used. */
