We're almost there actually. Retu is in great shape and tahvo is a lot
simpler, but it still needs help. Probably porting the changes I made on
retu would be the way to go.
A small TODO would be to use dev_pm_ops on all driver's suspend/resume
functions, then move retu-headset.c to Jack framework and port all
changes to tahvo as well.

heh, good luck and thanks for the initiative :-)
