  20 /* There are two bits of information that the driver needs in order
  21    to select the correct routing: the operating mode and the selection
  22    of the Y input (external or internal).
  23
  24    The first two operating modes expect a composite signal on the Y input,
  25    the second two operating modes use both the Y and C inputs.
  26
  27    Normally YCS_MODE is used for tuner and composite inputs, and the
  28    YCNR mode is used for S-Video inputs.
  29
  30    The external Y-ADC is selected when the composite input comes from a
  31    upd64031a ghost reduction device. If this device is not present, or
  32    the input is a S-Video signal, then the internal Y-ADC input should
  33    be used. */
