Merge tag 'fbdev-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux 

Pull fbdev updates from Tomi Valkeinen:

 - ssd1307fb: various fixes and improvements, SSD1305 support

 - use architecture agnostic functions instead of MTRR functions in
   various fbdev drivers

 - TI DRA7xx SoC display support (arch/arm/ side)

 - OMAPDSS componentization to fix probing order issues

 - OMAPDSS scaling fixes

 - msm_fb: remove obsoleted driver
