should be easy.  I assume form following comment, your a/d d/a use
I2C, no?

they are in ppc tree.  I haven't look at those driver, but ppc
currently have better xparameter.h support.  if those driver use some
defines which standalone/microblaze version doesn't have, it might be
a little bit work, but definitely feasible.

if you use linux i2c framework, it just read/write on a device node,
which is not defferent from reading/writing files.

hope this helps,
