For testing purposes it is sometimes handy to have a "dummy" codec on the other side of a DAI link with the CPU. In the case of ADSP that would be the SPORT. I think there might already be a means of doing this with existing kernel support, but it needs investigating. Failing that, for debug or hacky purposes, such a dummy driver can be offered.
