What I remember we need to convert drivers to use new API meanwhile it
is good to keep old one to avoid patch storm which does nothing useful
(IIRC Russel's opinion).

On the other hand there are a lot of drivers that are used on the set
of platforms starting from legacy and abandoned ones (like AVR32) to
relatively new and newest.

And I'm not a fan of those thousands of API calls either.
