Merge tag 'exynos-drm-next-for-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Summary:
- Rework vblank handling
  . This patch series adds frame counter callback and removes
    unnecessary pipe relevnt fields and simplifies event handling.
- clean up and fix up sw-trigger relevant code
  . This patch series moves TE relevant code from Panel and HDMI
    to DECON driver to fix a race between interrupt handlers and
    DECON disable, and to fix timeout issue at wait-for-vblank.
  . It removes unnecessary flags and check code specific to Exynos driver.
