Thanks for looking into this. 

Just a note, it sounded like they want to add cropping feature to this driver
later.

And a question, what I didn't understand, why is it necessary to probe all
possible mode combinations ahead of time anyway?

If I ask for 640x480 at 60fps, why does it need to iterate through all of them
to build these massive data structures? Why can't it just jump straight to that
requested mode?
