If you can deal with the lack of detailed documentation, UDD has the
advantage of implementing pretty much what you described
already. Conversely, writing your own driver may help if you need it to
handle specific aspects of the PRU which could not be easily done based
on the generic UDD mechanisms. YMMV.
