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 * tag 'fbdev-updates-for-3.6' of git://github.com/schandinat/linux-2.6: (78 commits) da8xx-fb: fix compile issue due to missing include fbdev: Make pixel_to_pat() failure mode more friendly da8xx-fb: do not turn ON LCD backlight unless LCDC is enabled fbdev: sh_mobile_lcdc: Fix vertical panning step video: exynos mipi dsi: Fix mipi dsi regulators handling issue video: da8xx-fb: do clock reset of revision 2 LCDC before enabling arm: da850: configure LCDC fifo threshold video: da8xx-fb: configure FIFO threshold to reduce underflow errors video: da8xx-fb: fix flicker due to 1 frame delay in updated frame video: da8xx-fb rev2: fix disabling of palette completion interrupt da8xx-fb: add missing FB_BLANK operations video: exynos_dp: use usleep_range instead of delay video: exynos_dp: check the only INTERLANE_ALIGN_DONE bit during Link Training fb: epson1355fb: Fix section mismatch video: exynos_dp: fix wrong DPCD address during Link Training video/smscufx: fix line counting in fb_write aty128fb: Fix coding style issues fbdev: sh_mobile_lcdc: Fix pan offset computation in YUV mode fbdev: sh_mobile_lcdc: Fix overlay registers update during pan operation fbdev: sh_mobile_lcdc: Support horizontal panning ...
