Why only two of us? Please don't work on old kernels, some ancient code.

Please use scripts/get_maintainers.pl to get a list of necessary people and lists to CC (and consider --no-git-fallback argument, so you will not CC people just because they made one commit years ago). It might happen, that command when run on an older kernel, gives you outdated entries. Therefore please be sure you base your patches on recent Linux kernel.

Tools like b4 or scripts/get_maintainer.pl provide you proper list of people, so fix your workflow. Tools might also fail if you work on some ancient tree (don't, instead use mainline) or work on fork of kernel (don't, instead use mainline). Just use b4 and everything should be fine, although remember about b4 prep --auto-to-cc if you added new patches to the patchset.

Actually I'm using master so the get_maintainer.pl output is fine, just wasn't using b4 and addding the CC myself, will resend with b4 and will update the patches per your review.

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[email protected]

The base for the series is generally the latest rc1. A different dependency should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.

The base for the series is generally the latest rc1. A different dependency should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date:

Quoted 5 lines

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.

Couldn't reproduce, I can't seem to see any error/warning that would be introduced by this patch, can the above be discarded then?

Anyway, please squash this and 3/5, it's just churn if boards are per-commit.

Node names should be generic. See also an explanation and list of examples (not exhaustive) in DT specification:

If you cannot find a name matching your device, please check in kernel sources for similar cases or you can grow the spec (via pull request to DT spec repo).
