Revert "drm/exynos/decon5433: implement frame counter" [ Upstream commit 6ca469e22a30992b4478d2ab88737c70667c1e00 ] This reverts commit 0586feba322e1de05075700eb4b835c8b683e62b This patch makes it to need get_vblank_counter callback in crtc to get frame counter from decon driver. However, drm_dev->max_vblank_count is a member unique to vendor's DRM driver but in case of ARM DRM, some CRTC devices don't provide the frame counter value. As a result, this patch made extension and clone mode not working. Instead of this patch, we may need separated max_vblank_count which belongs to each CRTC device, or need to implement frame counter emulation for them who don't support HW frame counter.
