I'm still not convinced that DCR access and variable register offsets
are needed - But it can always be added (through a seperate struct in
platform_data) - Patches are welcome.

The same with interrupt-less support if the changes are not too
intrusive.

Which is odd as I've gotten positive feedback from others.

Great.
