There is a newer version of this series
[v7 3/7] arm64: defconfig: Enable HIMAX_HX83102 panel
Posted by Cong Yang 1 year, 9 months ago
DRM_PANEL_HIMAX_HX83102 is being split out from DRM_PANEL_BOE_TV101WUM_NL6.
Since the arm64 defconfig had the BOE panel driver enabled, let's also
enable the himax driver.

You should probably sent this one separately since only an ARM SoC maintainer
can apply this, probably via the qcom tree.

Thanks,

Really? I always kinda figured that this was a bit like MAINTAINERS
where it can come through a bunch of different trees. Certainly I've
landed changes to it before through the drm-misc tree. If that was
wrong then I'll certainly stop doing it, of course.

Hi:

If it is determined that a separately patch needs to be sent, then I
will remove this patch in V8 series?

Yeah we usually don't mess with arch specific defconfig from drm tree

In general I agree that makes sense. In this case, though, the new
config symbol was introduced in the previous patch and split off an
existing symbol. Updating "all" of the configs (AKA just arm64) that
had the old symbol to also have the new symbol seems like the nice
thing to do and it feels like it makes sense to land in the same tree
that did the "split" just to cause the least confusion to anyone
affected.

In any case, if it's going to land in some other tree then I guess the
question is whether it needs to wait a few revisions to land there or
if it should land right away. Nobody would get a compile error if it
landed in a different tree right away since unknown config symbols are
silently ignored, but it feels a little weird to me.

...of course, I'm also OK just dropping the config patch. I personally
don't use the upstream "defconfig". It just seemed courteous to update
it for those who do.

Hmmm, probably should have put Arnd on this thread. Added now in case
he has any opinions. I also did manage to find when this last came up
where I was involved. At that time Will Deacon (who get_maintainer.pl
reports is the official maintainer of this file) said [1]:
