11/* There are two bits of information that the driver needs in order
12   to select the correct routing: the operating mode and the selection
13   of the Y input (external or internal).
14
15   The first two operating modes expect a composite signal on the Y input,
16   the second two operating modes use both the Y and C inputs.
17
18   Normally YCS_MODE is used for tuner and composite inputs, and the
19   YCNR mode is used for S-Video inputs.
20
21   The external Y-ADC is selected when the composite input comes from a
22   upd64031a ghost reduction device. If this device is not present, or
23   the input is a S-Video signal, then the internal Y-ADC input should
24   be used. */
