Not able to understand. You want IPQ9574 to use "qcom,ipq8074-tsens" instead of adding a "qcom,ipq9574-tsens" and no need to add an extra entry to the driver like }, { .compatible = "qcom,ipq9574-tsens", .data = &data_ipq8074, }, { Thanks Varada > Best regards, > Krzysztof >

With schema like this items: - enum: - qcom,ipq8074-tsens - qcom,ipq9574-tsens and DTS as compatible = "qcom,ipq9574-tsens", "qcom,ipq8074-tsens"; 'make dtbs_check' gives the following error arch/arm64/boot/dts/qcom/ipq9574-rdp433.dtb: thermal-sensor@4a9000: compatible: 'oneOf' conditional failed, one must be fixed: ['qcom,ipq9574-tsens', 'qcom,ipq8074-tsens'] is too long To fix the above error, I have to change the schema as items: - enum: - qcom,ipq8074-tsens - qcom,ipq9574-tsens - const: qcom,tsens-v2-combined-int and change ipq8074 & ipq9754 DTS as compatible = "qcom,ipq8074-tsens", "qcom,tsens-v2-combined-int"; compatible = "qcom,ipq9574-tsens", "qcom,tsens-v2-combined-int"; For this to work, have to introduce qcom,tsens-v2-combined-int in the driver with }, { .compatible = "qcom,tsens-v2-combined-int", .data = &data_ipq8074, }, This i guess will defeat the purpose. So shall we leave it as it is now, or shall I change driver, schema and ipq8074 + ip9574 DTS with qcom,tsens-v2-combined-int? Let me know. Thanks Varada > Best regards, > Krzysztof
