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.
