I should have looked a bit harder.

It is written for the iPAQ, which talks to it using 5 GPIO lines and
some EGPIO lines for power control. It doesn't seem to be wired up to
any of the audio stuff yet.

There are several drivers under hpc* that ought to have been written
to use bus space functions. The MQ200 and UCB1300 drivers from hpcmips
as well as this one.
