My plan was to enable prefetch engine support[1] for i.MX8QXP display
controller and add device tree for a whole i.MX8QXP LVDS display pipeline,
before adding i.MX95 display controller support.

Unfortunately, it seems that Marek is not a big fan of [1] and I'm busy
with downstream development so the plan doesn't move forward well.  I still
think [1] makes sense(maybe I need to rebase it on latest drm-misc-next),
so I'd like to see review comments on [1] and hopefully people think that
the overall idea of [1] is ok.

I still think that i.MX95 display controller driver should be in a separate
driver, rather than sharing the same driver with i.MX8QXP display controller
like this patch series does, because the two display controllers are quite
different as I mentioned in comments on this patch series and in discussion
in [1].  Also, the common part between the two display controllers should
be extracted to a common helper library as I mentioned there too.
