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. >> + >> + memory@0 { >> + device_type = "memory"; >> + reg = <0x0 0x40000000>; >> + }; >> +}; > >> +#include "skeleton.dtsi" > > Please don't include skeleton.dtsi. 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? :) > Please add the relevant nodes and > properties explciitly to your dts{i,} files. 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

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. > > Please add the relevant nodes and > > properties explciitly to your dts{i,} files. > > Great, will do. > > But this series has grown too large to resend just for such nits.

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.
