Merge tag 'exynos-drm-next-for-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos

 into drm-next

Cleanups
- Change g2d driver to component based driver
  . g2d driver was last customed sub driver so this patch series
    changes it to component based driver, which also makes gem handling
    to be more simplify.
- Cleanup of Exynos DRM suspend/resume
  . Register exynos drm core suspend/resume functions
    to prepare/complete callbacks of dev_pm_ops instead of suspend/resume
    callbacks to ensure exynos_drm_suspend() is called before any suspend
    callback from the real devices to avoid some issues on boards with
    complex pipelines.
  . Also Add pm_runtime_furce_suspend/resume as SYSTEM_SLEEP_PM_OPS
    to ensure that resources of each devices will be released
    for the system PM suspend/resume cycle.
- Remove local value not used.
