[PATCH v2 0/8] drm/vc4: Add support for the transposer IP

[Boris Brezillon]

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
