Please don't include skeleton.dtsi. Please add the relevant nodes and
properties explciitly to your dts{i,} files.

Please define your #address-cells and #size-cells here.
If you want, add an empty /chosen node (not strictly necessary since
your dts file has a non-empty one anyhow).
Thanks,
Mark.

I guess so: Working around its hardcoded name without unit address, not
finding a /rename-node/ to that effect.

Wasn't aware that was permissible. I now see it has been updated with a
textual comment, which predates my past uses of skeleton.dtsi - for
other pending work such as FM4 and XMC4500 I only noticed it was moved
out of armv7m.dtsi so that dtc started spewing scary messages. ;)
A #warning might be a more effective way to make people aware of its
deprecation - but sadly we have users that predate #include:
$ git grep /include/ -- arch/arm/boot/dts/ | grep skeleton.dtsi | wc --lines
32
$ git grep /include/ -- arch/arm/boot/dts/ | grep skeleton64.dtsi | wc
--lines
0
$ git grep skeleton -- arch/arm/boot/dts/ | wc --lines
117
Might updating those 32 users be a suitable Outreachy project (CC'ed),
to then get the remaining 85 occurrences to be eliminated by their
maintainers, so that it doesn't get copied for new SoCs any more? :)

Great, will do.
But this series has grown too large to resend just for such nits. Is
there a chance we can get initial patches queued on some arm-soc
for-next branch soonish? It seems -rc1 pulls were merged 5 days ago?
Regards,
Andreas

I deliberately didn't go that route, since people would blindly fix up
the warning and mess it up (e.g. forgetting to add the required nodes).
While it should be avoided for new dts, it's largely not problematic for
old dts, and we can fix those up at our leisure.

There seem to be other comments on this series, and I was under the
impression that arm-soc generally pulled branches.
Even if you're not going to repost, surely you can fold in the fixup
before sending the pull request?
Thanks,
Mark.
