What is needed for diy audio is a general purpose I2S driver which can have its parameters set by editing a text file.

We would need to be able to choose master/slave and I2S, left-justified or right-justified output format. We would also need some i/o pins to indicate sample rate and, if someone really wanted to go to town, DSD and muting flags.

The HiFiBerry products appear to use I2C to identify the board so, as I understand it, unless it gets back the right response the output will not work.

Yes would be great to have.
Do you have the skills to program a kernel driver for it?
