Merge tag 'fbdev-updates-for-3.4' of git://github.com/schandinat/linux-2.6

Pull fbdev updates for 3.4 from Florian Tobias Schandinat:
 - drivers for Samsung Exynos MIPI DSI and display port
 - i740fb to support those old Intel chips
 - large updates to OMAP, viafb and sh_mobile_lcdcfb
 - some updates to s3c-fb and udlfb, few patches to others

Fix up conflicts in drivers/video/udlfb.c due to Key Sievers' fix making
it in twice.
