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).
