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. */
