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
