/* 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. */
