Merge tag 'fbdev-updates-for-3.6' of git://github.com/schandinat/linux-2.6
Pull fbdev updates from Florian Tobias Schandinat:
- large updates for OMAP
- support for LCD3 overlay manager (omap5)
- omapdss output cleanup
- removal of passive matrix LCD support as there are no drivers for
such panels for DSS or DSS2 and nobody complained (cleanup)
- large updates for SH Mobile
- overlay support
- separating MERAM (cache) from framebuffer driver
- some updates for Exynos and da8xx-fb
- various other small patches
