+/* 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. */
