[PATCH 0/4] drm/exynos: rework vblank handling

[Andrzej Hajda <a.hajda@samsung.com>]

Hi Inki,

This patchset fixes long standing issue with occassional page faults
or vblank event timeouts on TM2 targets due to delayed vblank handling.
DECON driver should now handle properly all scenarios described in drm
docs [1][2], at least it was my intention.

I have successfully tested it on TM2 panel, TV and both.
