Greetings,

I am interested in using the gpio and i2c for a couple of 
upcomming projects.

If I have a seperate device driver and I want to do some
reads/writes on these busses, then can I use call the
bttv driver to access the ports?

Is the access granted from user space also?

I see that device drivers can call other device drives ( such
as v4l driver registration), so I should not be a problem.

Has anybody done anything like this?  

What kinds of data rates can I expect on the gpio bus?

Any gotchas?
