Merge tag 'drm-next-2018-12-27' of git://anongit.freedesktop.org/drm/drm

Pull more drm updates from Dave Airlie:
 "Daniel collected a couple of pulls after I want on holidays, back for
  a couple of days, so may as well send them out.

  This has exynos and etnaviv work for 4.21.

  exynos:
   - plane alpha and blending configurability

  etnaviv:
   - mostly cleanups in prep for new features"

* tag 'drm-next-2018-12-27' of git://anongit.freedesktop.org/drm/drm:
  drm/etnaviv: remove lastctx member from gpu struct
  drm/etnaviv: replace header include with forward declaration
  drm/etnaviv: remove unnecessary local irq disable
  drm/exynos: fimd: Make pixel blend mode configurable
  drm/exynos: fimd: Make plane alpha configurable
  drm/etnaviv: Replace drm_dev_unref with drm_dev_put
  drm/etnaviv: consolidate hardware fence handling in etnaviv_gpu
  drm/etnaviv: kill active fence tracking
