Why add 'rockchip,system-power-controller' while also adding
'system-power-controller'?
Property 'rockchip,system-power-controller' was deprecated in commit
961748bb1555 ("dt-bindings: mfd: rk8xx: Deprecate rockchip,system-power-controller")
And because of that I submitted this patch/commit:
b99ac7e2a1cc ("arm64: dts: rockchip: Drop rockchip prefix of s-p-c PMIC prop from rk356x")
to replace the deprecated variant with the non-deprecated one.
Cheers,

Please use scripts/get_maintainers.pl to get a list of necessary people and lists to CC. It might happen, that command when run on an older kernel, gives you outdated entries.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. You missed at least devicetree list (maybe more), so this won't be tested by automated tooling. Performing review on untested code might be a waste of time. Please kindly resend and include all necessary To/Cc entries. 2. Node names should be generic. See also an explanation and list of examples (not exhaustive) in DT specification: https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation 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). 3. Underscore is not allowed in node names. Neither capital letters. Please read DTS coding style. Best regards, Krzysztof
