[PATCH v3 0/9] drm/vc4: Add support for the transposer IP

[Boris Brezillon]

Hello,

This is the third 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 the core that I had to add to make it work on VC4.

Not much has changed in this v3, just a few minor fixes/cleanup/rework
and the addition of one patch to make commit->atomic_commit() optional.
See the changelog in each patch you want more details.

Regards,

Boris
