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,
