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/)"
