Merge tag 'fbdev-updates-for-3.7' of git://github.com/schandinat/linux-2.6

Pull fbdev updates from Florian Tobias Schandinat:
 "This includes:
   - large updates for OMAP
     - basic OMAP5 DSS support for DPI and DSI outputs
     - large cleanups and restructuring
   - some update to Exynos and da8xx-fb
   - removal of the pnx4008 driver (arch removed)
   - various other small patches"

Fix up some trivial conflicts (mostly just include line changes, but
also some due to the renaming of the deferred work functions by Tejun).
