Well, recently I've sent a couple of patches which implement stuff from
TODO [1]. However, with the migration to DT, my focus now is to have a
kernel/userspace that boots at all and this leaves no free cycles for
DSP. Maybe tidspbridge can be left in staging until DT migration is
finished, that way me (and maybe other people) will have the time needed
to try to implement what remains in TODO. Also, keep in mind there will
(hopefully) be another omap3 end-user device released by the end of the
year (Neo900), which most probably will gain more developers interested
in fixing the DSP driver.

Regards,
Ivo
