  24/* There are two bits of information that the driver needs in order
  25   to select the correct routing: the operating mode and the selection
  26   of the Y input (external or internal).
  27
  28   The first two operating modes expect a composite signal on the Y input,
  29   the second two operating modes use both the Y and C inputs.
  30
  31   Normally YCS_MODE is used for tuner and composite inputs, and the
  32   YCNR mode is used for S-Video inputs.
  33
  34   The external Y-ADC is selected when the composite input comes from a
  35   upd64031a ghost reduction device. If this device is not present, or
  36   the input is a S-Video signal, then the internal Y-ADC input should
  37   be used. */
