How can #define be added after its usage? Does it even make any sense of being separate patch? Do you folks in Mediatek have any internal review before posting? Best regards, Krzysztof
Hi Krzysztof, Thanks for the reviews.

Do you mean I should merge this patch into the [PATCH 9/15]? > Do you folks in Mediatek have any internal review before posting? We'll use a robot to scan the whole series for the DT_CHECK, checkpatch, build warning and build error, etc, before sending patches. I'm sorry about bothering you to take time on reviewing these patches. But it seems the robot can't scan out which patches should be separated or merged together. It there any rules or scripts that can train the robot to know how it goes? Regards, Jason-JH.Lin > > Best regards, > Krzysztof > >

The example of dts in patch 1 is used the definition of mt8188, so I think I can add this patch to define the gce event id for mt8195 after patch 1. I will swap the patch 1 and the patch 2 in the next version, if that can make it more appropriate. Regards, Jason-JH.Lin > Best regards, > Krzysztof > >

Really, test your patches. Each of them individually. Appropriateness is one thing, but broken bisectability is an error. Anyway, the patch is logically part of binding adding this, so it should be squashed. Don't create some weird patch ordering where every define or every function is in its own patch. I commented about it multiple times in this patchset. Best regards, Krzysztof
