A different dependency should be noted in *this* patch. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments. If you already ran DT checks and didn't see these error(s), then make sure dt-schema is up to date: pip3 install dtschema --upgrade New warnings running 'make CHECK_DTBS=y adi/sc598-som-ezkit.dtb' for 20240912-test-v1-0-458fa57c8ccf@analog.com: arch/arm64/boot/dts/adi/sc598-som-ezkit.dtb: /scb-bus/sec@31089000: failed to match any schema with compatible: ['adi,system-event-controller']

I've done a first pass of a review now, but the drivers will all need a more detailed review from the subsystem maintainers as well. For the drivers/soc and include/linux/soc portions, I need to do second review round when you have added a description about what these are used for, ideally I would hope that most of those can disappear from the final series when the required bits are moved into other drivers. I commented on one of the bindings about the compatible string, but later saw that the same issue is present in all of the bindings, which each need a more specific identifier for a particular piece of hardware they are compatible with.

Shouldn't a reset controller use the reset binding (i.e. #reset-cells)? All you patches seem to have similar issues, so I'm not going to comment on all of them. Please read the documentation in Documentation/devicetree/bindings/. It doesn't seem like you have. Rob

Please run standard kernel tools for static analysis, like coccinelle, smatch and sparse, and fix reported warnings. 2. Also check for warnings when building with W=1. Most of these commands (checks or W=1 build) can build specific targets, like some directory, to narrow the scope to only your code. The code here looks like it needs a fix. Feel free to get in touch if the warning is not clear. 3. Fix all compile test warning reported by LKP and check for common configs, regardless of reports. 4. Please run `make dtbs_check W=1` (see Documentation/devicetree/bindings/writing-schema.rst or https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/ for instructions). 5. 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. Best regards, Krzysztof
This set of patches based on ADI fork of Linux Kerenl that support family of ADSP-SC5xx SoC's and used by customers for some time . Patch series contains minimal set of changes to add ADSP-SC598 support to upstream kernel. This series include UART,I2C,IRQCHIP,RCU drivers and device-tree to be able boot on EV-SC598-SOM board into serial shell and able to reset the board. Current SOM board requires I2C expander to enable UART output. UART,I2C and PINCTRL drivers are based on old Blackfin drivers with ADSP-SC5xx related bug fixes and improvments.
