[PATCH 0/8] vc4: Convert to drm_atomic_helper_commit

[Maxime Ripard]

Hi,

Here's a conversion of vc4 to remove the hand-rolled atomic_commit helper from
vc4 in favour of the generic one.

This requires some rework of vc4, but also a new hook and some documentation
for corner-cases in the DRM core that have been reported and explained by
Daniel recently.

Let me know what you think,
Maxime
