> VIDI driver uses fake vblank handler to generate vblank events.
> It was implemented using worker which slept for vblank time, additionally
> it did not work if there were no page flips. The patch replaces it with
> timer, uses drm_crtc_vblank_(on|off) helpers to manage it and fixes
> behavior for non-page-flip cases.
> This change allows further improvements of vblank in exynos-drm framework.
