This is exactly what Lars-Peter did, he updated all the drivers that
used cyclic mode to use the framework.  Drivers using non-cyclic mode
weren't updated as there is some additional work needed in the
framework.

That said, you don't always want to do this - depending on the change
involved it's sometimes simpler and easier to move things over piecemeal
unless there's an actual issue being created by the lack of the new
firmware.
