It's already in snps,dwmac. Actually this applies to several other properties. You have unevaluatedProperties:false, so you do not have to duplicate snps,dwmac.

I was actually getting errors like the following without the same: arm64/boot/dts/qcom/qcs404-evb-1000.dtb: ethernet@7a80000: Unevaluated properties are not allowed ('snps,tso' was unexpected) From schema: Documentation/devicetree/bindings/net/qcom,ethqos.yaml So, its not clear to me that even though 'snps,dwmac.yaml' is referenced here, the property appears as unevaluated. >> + >> + power-domains: >> + maxItems: 1 >> + >> + resets: >> + maxItems: 1 >> + >> + rx-fifo-depth: >> + $ref: /schemas/types.yaml#/definitions/uint32 >> + >> + tx-fifo-depth: >> + $ref: /schemas/types.yaml#/definitions/uint32 >> + >> + snps,tso: >> + type: boolean >> + description: Enables the TSO feature (otherwise managed by MAC HW capability register). > > You add here several new properties. Mention in commit msg changes from > pure conversion with answer to "why". Right, most of them are to avoid the make dtbs_check errors / warnings like the one mentioned above. I will add a comment in the commit log regarding the same. Thanks, Bhupesh

I guess only 'snps,reset-gpio' need not be replicated here, as for others I still see 'dtbs_check' error, if they are not replicated here: arch/arm64/boot/dts/qcom/sm8150-hdk.dtb: ethernet@20000: Unevaluated properties are not allowed ('power-domains', 'resets', 'rx-fifo-depth', 'tx-fifo-depth' were unexpected) From schema: /Documentation/devicetree/bindings/net/qcom,ethqos.yaml Am I missing something here? Thanks.

Probably the snps,dwmac schema failed. It is then considered unevaluated, so such properties are unknown for qcom,ethqos schema. Run check with snps,dwmac and fix all errors first.

Running dt_binding_check DT_SCHEMA_FILES=net/snps,dwmac.yaml reports no error currently. Thanks.

I don't know what you wrote, as you did not sent a commit. I cannot reproduce your errors after removing unneeded power-domains. Just to clarify - I am testing only the dt_binding_check (so only the examples - I assume they are meaningful). Best regards, Krzysztof

Just a little note before I forget.. I picked this up yesterday (in prep for adding sa8540p support here), and noticed the same thing as Bhupesh when validating dtbs with the requested changes (not duplicating snsp,dwmac.yaml). I ended up tracking it down to a (fixed) bug in dtschema: https://github.com/devicetree-org/dt-schema/commit/e503ec1115345bdfa06b96c9d6c4496457cbd75b And a little test output showing before and after (fix is in the 2022.12 release): (dtschema-2022.11) ahalaney@halaney-x13s ~/git/redhat/stmmac (git)-[stmmac] % make CHECK_DTBS=y DT_SCHEMA_FILES=/net/qcom,ethqos.yaml qcom/sm8150-hdk.dtb LINT Documentation/devicetree/bindings CHKDT Documentation/devicetree/bindings/processed-schema.json SCHEMA Documentation/devicetree/bindings/processed-schema.json DTC_CHK arch/arm64/boot/dts/qcom/sm8150-hdk.dtb /home/ahalaney/git/redhat/stmmac/arch/arm64/boot/dts/qcom/sm8150-hdk.dtb: ethernet@20000: Unevaluated properties are not allowed ('power-domains', 'resets', 'rx-fifo-depth', 'snps,tso', 'tx-fifo-depth' were unexpected) From schema: /home/ahalaney/git/redhat/stmmac/Documentation/devicetree/bindings/net/qcom,ethqos.yaml (dtschema-2022.11) ahalaney@halaney-x13s ~/git/redhat/stmmac (git)-[stmmac] % pip3 list | grep dtschema dtschema 2022.11 (dtschema-2022.11) ahalaney@halaney-x13s ~/git/redhat/stmmac (git)-[stmmac] % dtschema) ahalaney@halaney-x13s ~/git/redhat/stmmac (git)-[stmmac] % pip3 list | grep dtschema dtschema 2023.1 (dtschema) ahalaney@halaney-x13s ~/git/redhat/stmmac (git)-[stmmac] % make CHECK_DTBS=y DT_SCHEMA_FILES=/net/qcom,ethqos.yaml qcom/sm8150-hdk.dtb LINT Documentation/devicetree/bindings CHKDT Documentation/devicetree/bindings/processed-schema.json SCHEMA Documentation/devicetree/bindings/processed-schema.json DTC_CHK arch/arm64/boot/dts/qcom/sm8150-hdk.dtb (dtschema) ahalaney@halaney-x13s ~/git/redhat/stmmac (git)-[stmmac] % I'll go ahead and make the adjustments and pull this series into mine adding sa8540p support, thanks for starting it! - Andrew
