Hello,

This patch series is the sixth attempt to (nearly, see [1]) complete the
rework of the omapdrm driver to move to drm_bridge and drm_panel.

Version 2, available at [2], explains in its long cover letter the
rationale for the changes. I won't duplicate it here as it is still
valid as-is.

Compared to v5, available at [3], this version has been rebased on top
of drm-misc-next, and minor bugs have been fixed, including interlaced
modes support with VENC.

The patches can be found at

        git://linuxtv.org/pinchartl/media.git omapdrm/bridge/devel

[1] The only notable exception is the omapdrm-specific DSI panel driver
that implements a large number of custom operations. This is being
addressed separately.

The series is

Testing was done on Droid 4, DSI command mode panel is still
working. I had to add the following patch because of the base
you chose for the branch. Might make sense to use 5.6-rc1 instead.

I had initially based it on drm-next, but there are changes in
drm-misc-next that were conflicting, hence the rebase.
