FWIW I have this at the moment:

I see that the card is there, but I'm fighting buildroot to have nfs
filesystem with aplay :o

There are few things going to be needed to get things in a shape, like
converting the sound/soc/omap/n810.c to platform driver to be probed via DT.
Proper bindings for the card,
support for mclk handling in aic3x codec driver (n810 is hackinig that in the
machine driver)

In theory audio _should_ work with the DT changes and the fixup in the n810.c...

Should...
