This series tries to do that. The first patch adds all necessary data structures to ecovec24. Patch 2/7 unifies much of the code for both pdata and non-pdata cases. Patches 3-4/7 remove unused platform data fields. Last three patches contain additional improvements for the GPIO backlight driver while we're already modifying it. I don't have access to this HW but hopefully this works. Only compile tested.
