Do you have an example of such a use case?  If you can do that it feels
more like one end has two single direction DAIs (ISTR some of the
Freescale platforms were built like that?) and it might be better to do
that and make it easier to combine two DAIs.  That would also work for
things like combining dedicated DACs and ADCs.
