Subject: [PATCH v9 00/11] Genericize DW MIPI DSI bridge and add i.MX 6 driver

[Re-submitting to cc dri-devel, sorry about the noise]

Hello all,

v9 cleanly applies on top of latest next-20200609 tree.

v9 does not depend on other patches as the last binding doc has been merged.

All feedback up to this point has been addressed. Specific details in
individual patch changelogs.

The biggest changes are the deprecation of the Synopsys DW bridge bind()
API in favor of of_drm_find_bridge() and .attach callbacks, the addition
of a TODO entry which outlines future planned bridge driver refactorings
and a reordering of some i.MX 6 patches to appease checkpatch.

The idea behind the TODO is to get this regmap and i.MX 6 driver merged
and then do the rest of refactorings in-tree because it's easier and the
refactorings themselves are out-of-scope of this series which is adding
i.MX 6 support and is quite big already, so please, if there are more
refactoring ideas, let's add them to the TODO doc. :) I intend to tackle
those after this series is merged to avoid two complex inter-dependent
simultaneous series.

As always more testing is welcome especially on Rockchip and STM SoCs.

Big thank you to everyone who has contributed to this up to now,
Adrian
