I'm going to pull this out until it gets sorted out. Also, could you rebase on the latest kernel when submitting next time? There was a minor thing I had to fix up. -corey > > kcs@114: 'clocks' is a required property > arch/arm/boot/dts/aspeed-bmc-amd-ethanolx.dt.yaml > arch/arm/boot/dts/aspeed-bmc-bytedance-g220a.dt.yaml > arch/arm/boot/dts/aspeed-bmc-inspur-nf5280m6.dt.yaml > > kcs@24: 'clocks' is a required property > arch/arm/boot/dts/aspeed-bmc-amd-ethanolx.dt.yaml > > kcs@28: 'clocks' is a required property > arch/arm/boot/dts/aspeed-bmc-amd-ethanolx.dt.yaml > arch/arm/boot/dts/aspeed-bmc-facebook-elbert.dt.yaml > arch/arm/boot/dts/aspeed-bmc-facebook-tiogapass.dt.yaml > > kcs@2c: 'clocks' is a required property > arch/arm/boot/dts/aspeed-bmc-amd-ethanolx.dt.yaml > arch/arm/boot/dts/aspeed-bmc-asrock-e3c246d4i.dt.yaml > arch/arm/boot/dts/aspeed-bmc-bytedance-g220a.dt.yaml > arch/arm/boot/dts/aspeed-bmc-facebook-elbert.dt.yaml > arch/arm/boot/dts/aspeed-bmc-facebook-tiogapass.dt.yaml > arch/arm/boot/dts/aspeed-bmc-inspur-nf5280m6.dt.yaml >

Is it a result after applying all changes in this series or just after cherry picking #5/6 patch only? I tested 'dtbs_check' before submitting this series I tested it again and got the same good result like below. Aren't the above warnings false positive? Or did I miss something?

I'll submit v3 after rebasing it on the latest master when all queued changes in '-next' are merged. It would be also good for reducing confusions if any.

Or did I miss something? What you missed is this is an ABI. You cannot make something required that was not required before. If the driver follows the schema and makes 'clocks' required, then old DTBs with a new kernel will break. It's possible that 'clocks' was always required or that it never worked without clocks, then this change is okay. Looking at this patch, I have no way to know that. The commit message has to explain that. A commit message needs to answer WHY are you making the change. You don't really need WHAT the change is as anyone can read the diff. Rob

Would it be good enough if I add more detail commit message including a note that dtb recompiling is required? Or, should I change this series to treat the 'clocks' as an optional property? Can you please share your thought? Thanks, Jae > Rob >

Can you please share your thought? Make it essential. It was only by accident that things have worked without this change. While keeping backwards compatibility with dtbs is a goal we strive for, in practice we use the dtb from the corresponding kernel source tree, so as long as the patch to the driver is applied in the same place as the patch to the device tree no systems will break.

Okay. I'll keep 'clocks' property as a required property and will make the commit message of this patch more descriptive. Thanks a lot for your feedback. Cheers, Jae
