Hi Angelo,

This series was tested on MT8195 Cherry Tomato and on MT8395 Radxa
NIO-12L with both hardcoded paths, OF graph support and partially
hardcoded paths (meaning main display through OF graph and external
display hardcoded, because of OVL_ADAPTOR).

Is that make sense for you to add the DTS changes of these boards into this 
serie ?
I asked because, IMHO, that could help to understand the serie.


Yes and no... but I imagine that you're asking this because you're trying to
prepare something with a different SoC+board(s) combination :-)

In that case, I'm preventively sorry because what follows here is not 100%
perfectly tidy yet as I didn't mean to send the devicetree commits upstream
before this series got picked....

... but there you go - I'm sure that you won't mind and that the example will
be more than good enough for you.

Please note that one of the reasons why I didn't want to add this to the series
is that the following changes show only a mere 50% of the reasons why we want OF
graph support on mediatek-drm (but mainly, it's because I didn't have time to
actually rebase etc :-P )


Cheers!
Angelo
