Say Y or M if you want to add support for codecs attached to
the Blackfin SPORT (synchronous serial ports) interface in slot 16
mode (pseudo AC97 interface).
You will also need to select the audio interfaces to support below.
Note:
AC97 codecs which do not implement the slot-16 mode will not function
properly with this driver. This driver is known to work with the
Analog Devices line of AC97 codecs.
