/* 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. */
