Merge tag 'fbdev-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux
Pull fbdev updates from Tomi Valkeinen: "Summary: - pxafb: device-tree support - An unsafe kernel parameter 'lockless_register_fb' for debugging problems happening while inside the console lock - Small miscellaneous fixes & cleanups - omapdss: add writeback support functions - Separation of omapfb and omapdrm (see below) About the separation of omapfb and omapdrm, see http://permalink.gmane.org/gmane.comp.video.dri.devel/143151 for longer story. The short version: omapfb and omapdrm have shared low level drivers (omapdss and panel drivers), making further development of omapdrm difficult. After these patches omapfb and omapdrm have their own versions of the drivers, which are more or less direct copies for now but will diverge soon. This also means that omapfb (everything under drivers/video/fbdev/omap2/) is now in maintenance mode, and all new development will be done for omapdrm (drivers/gpu/drm/omapdrm/)" * tag 'fbdev-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux: (49 commits) video: fbdev: pxafb: fix out of memory error path drm/omap: make omapdrm select OMAP2_DSS drm/omap: move omapdss & displays under omapdrm omapfb: move vrfb into omapfb omapfb: take omapfb's private omapdss into use omapfb/displays: change CONFIG_DISPLAY_* to CONFIG_FB_OMAP2_* omapfb/dss: change CONFIG_OMAP* to CONFIG_FB_OMAP* omapdss: remove CONFIG_OMAP2_DSS_VENC from omapdss.h omapfb: copy omapdss & displays for omapfb omapfb: allow compilation only if DRM_OMAP is disabled fbdev: omap2: panel-dpi: simplify gpio setting fbdev: omap2: panel-dpi: in .disable first disable backlight then display OMAPDSS: DSS: fix a warning message video: omapdss: delete unneeded of_node_put OMAPDSS: DISPC: Remove boolean comparisons OMAPDSS: DSI: cleanup DSI_IRQ_ERROR_MASK define OMAPDSS: remove extra out == NULL checks OMAPDSS: change internal dispc functions to static OMAPDSS: make a two dss feat funcs internal to omapdss OMAPDSS: remove extra EXPORT_SYMBOLs ...
