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?

Andreas
