I speak about branches. You quoted submitting patches in DT, but that is implied. I already know it, I was making changes there and I already use that document as arguments in multiple discussion, so please assume I know it and my comments reflect that knowledge. I actually assumed that you also knew it. DT binding patch should go with the patch using the binding. So DT binding for board is clearly a DTS branch patch. > >>> dt-bindings: soc: renesas: renesas,rzg2l-sysc: Document RZ/G3L SoC >> >> This is drivers.

Then this should not be a separate branch, because: 1. No benefits - you did not solve any soft dependency. Your DTS branch is non-bisectable from dtbs_check point of view and you as maintainer of that tree should try to make it bisectable, meaning: "bindings go before user" like explained in what you quoted further. And please also read rest of submitting patches, although it is in part for "submitters" but explains the concept: " 5) The Documentation/ portion of the patch should come in the series before the code implementing the binding." "6) Any compatible strings used in a chip or board DTS file must be previously documented in the corresponding DT binding file" Previously means "before", so your DTS branch is failing above. 2. It is additional effort to handle this, because instead of merging one branch, I need to merge two. > >> See also submitting patches in DT dir. > > So the second commit is subject to II.3: > > 3) For a series going through multiple trees, the binding patch should be > kept with the driver using the binding. > > In this particular case, I could have included it in my drivers branch. > Where do I put SoC-specific DT binding changes that are not picked > up by anyone else (I don't have any this time)? What is "SoC-specific"? You put the DT binding with the user, that was always the rule and that is implied by submitting patches. If you do not have any user, why would you pick that up?
