Merge tag 'fbdev-v4.18' of git://github.com/bzolnier/linux

Pull fbdev updates from Bartlomiej Zolnierkiewicz:
 "There is nothing really major here, few small fixes, some cleanups and
  dead drivers removal:

   - mark omapfb drivers as orphans in MAINTAINERS file (Tomi Valkeinen)

   - add missing module license tags to omap/omapfb driver (Arnd
     Bergmann)

   - add missing GPIOLIB dependendy to omap2/omapfb driver (Arnd
     Bergmann)

   - convert savagefb, aty128fb & radeonfb drivers to use msleep & co.
     (Jia-Ju Bai)

   - allow COMPILE_TEST build for viafb driver (media part was reviewed
     by media subsystem Maintainer)

   - remove unused MERAM support from sh_mobile_lcdcfb and shmob-drm
     drivers (drm parts were acked by shmob-drm driver Maintainer)

   - remove unused auo_k190xfb drivers

   - misc cleanups (Souptick Joarder, Wolfram Sang, Markus Elfring, Andy
     Shevchenko, Colin Ian King)"

* Layout is based on skeletonfb.c by James Simmons and Geert Uytterhoeven.
*
* This driver is written to be used with the AUO-K1901 display controller.
*
* It is intended to be architecture independent. A board specific driver
* must be used to perform all the physical IO interactions.
*
* The controller supports different update modes:
* mode0+1 16 step gray (4bit)
* mode2+3 4 step gray (2bit)
* mode4+5 2 step gray (1bit)
* - mode4 is described as "without LUT"
* mode7 automatic selection of update mode
*
* The most interesting difference to the K1900 is the ability to do screen
* updates in an asynchronous fashion. Where the K1900 needs to wait for the
* current update to complete, the K1901 can process later updates already.
