Exynos DRM framework handled page-flip event with custom code. The patch replaces it with drm-core vblank queue. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> --- Hi Inki, This patch is next step of vblank re-factoring in Exynos-DRM. I have tested the code on fimd, vidi, decon5433, mixer. I hope I have not introduced bugs.
