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). * tag 'fbdev-updates-for-3.7' of git://github.com/schandinat/linux-2.6: (193 commits) gbefb: fix compile error video: mark nuc900fb_map_video_memory as __devinit video/mx3fb: set .owner to prevent module unloading while being used video: exynos_dp: use clk_prepare_enable and clk_disable_unprepare drivers/video/exynos/exynos_mipi_dsi.c: fix error return code drivers/video/savage/savagefb_driver.c: fix error return code video: s3c-fb: use clk_prepare_enable and clk_disable_unprepare da8xx-fb: save and restore LCDC context across suspend/resume cycle da8xx-fb: add pm_runtime support video/udlfb: fix line counting in fb_write OMAPDSS: add missing include for string.h OMAPDSS: DISPC: Configure color conversion coefficients for writeback OMAPDSS: DISPC: Add manager like functions for writeback OMAPDSS: DISPC: Configure writeback FIFOs OMAPDSS: DISPC: Configure writeback specific parameters in dispc_wb_setup() OMAPDSS: DISPC: Configure overlay-like parameters in dispc_wb_setup OMAPDSS: DISPC: Add function to set channel in for writeback OMAPDSS: DISPC: Don't set chroma resampling bit for writeback OMAPDSS: DISPC: Downscale chroma if plane is writeback OMAPDSS: DISPC: Configure input and output sizes for writeback ...
