/* 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. */
