Merge tag 'fbdev-3.12-omap-legacy-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux
Pull OMAP specific fbdev changes from Tomi Valkeinen:
"I've got this pull request separate from the main fbdev pull request,
as this contains a bunch of OMAP board file changes and thus could
possibly be rejected in case of bad conflicts.
The removal of the old display drivers depend on the board file
changes, so Tony Lindgren suggested taking them together via fbdev
tree. These are in linux-next, and also Tony didn't see any conflicts
with any of the branches he had, so they should go in clean.
- Change the OMAP board files to use the new OMAP display drivers
- Remove all the old drivers, and the related auxiliary code"
