Please run scripts/checkpatch.pl and fix reported warnings. Then please run 'scripts/checkpatch.pl --strict' and (probably) fix more warnings. Some warnings can be ignored, especially from --strict run, but the code here looks like it needs a fix. Feel free to get in touch if the warning is not clear. Best regards, Krzysztof

Yeah, it is not clear what do you want me to do, assuming the previous similar change to sun50i-a64-ccu.h did essentially the same, see 71b597ef5d46a326fb0d5cbfc1c6ff1d73cdc7f9 Regards, Vasily > Best regards, > Krzysztof >

As long as the #define's are not conflicting, this is fine. Then remove the now redundant definitions in the kernel headers, with a subsequent patch.

Yes, that would be a way to make it formally correct, but also much less readable and understandable later, as part of the source code repository. FWIW, I find this to be an example of the form being more important than the actual function. >> > Please run scripts/checkpatch.pl and fix reported warnings.

Not sure I understand your last sentence, exactly, but what Krzysztof pointed out is that one part (the header change in include/dt-bindings) is a DT binding patch, so part of a spec, if you like, the other is Linux *code*. There is the DT rebasing repo, which cherry-picks DT patches, so they form a separate history there, and Linux code has no place in there. U-Boot for instance pull this repo now on a regular basis. So keeping those things strictly separate is really important here. Cheers, Andre. > >> > Please run scripts/checkpatch.pl and fix reported warnings.

Thanks a lot for your detailed explanation and for reminding me about the DT rebasing repository. [*] I forgot about it for a moment, despite being active in U-Boot development when the repository was introduced, so yes, you're right that we're now in need to keep the bindings and the kernel code separate in patches. However, I can't stop myself from noticing that the way Krzysztof replied left a lot to be desired when it comes to friendliness in general. Such an approach is probably what contributed to me forgetting about the DT rebasing repository for a moment.

I'll address it in v2.
