Hello,
This is the second version of this series adding writeback support
to the VC4 display engine.
This version is based on drm-misc-next and include a bunch of
modifications to core that I had to add to make it work on VC4.
Feel free to comment on those modifications.
On the driver side, no much has changed except I modified a bit
the implementation to adjust the latest revision of the writeback
interface.
Regards,
Boris

drm/vc4: Use wait_for_flip_done() instead of wait_for_vblanks()
drm/crtc: Add a generic infrastructure to fake VBLANK events
drm/atomic: Call drm_atomic_helper_fake_vblank() from the generic
commit_tail() helpers
drm/vc4: Call drm_atomic_helper_fake_vblank() in the commit path
