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

[Neil Armstrong <narmstrong@baylibre.com>]

Hi Heiko,

Do you think someone can have a try of this patchset on a RK SoC ?

Thanks,
Neil

>>> [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
