I've been away for two and a half weeks so I haven't been able to

But before I start to make changes, I'd still like to ask for a comment
on my original plan, which was to have the I/O functions in the MFD
driver and also have there things like interrupt handling etc.

My vision was that the MFD part would have the application logic and the
child drivers would be just true interfaces to the core functionality,
because I kind of saw the children to be of equal importance and because
the codec and the v4l2 driver share some controls like for example the
volume control. 

If you'd care to take a look an earlier version of the MFD driver here:


So the question is if I put only the I/O stuff into the MFD driver or
can I have the other application logic there as well?
