The read-only match-data path looks fine, but it should be integrated with the existing LUT match data. We should not replace the current match-data usage. > - Should the pending Lenovo binding omit the qcom,hamoa-crd-ec fallback, > given that this firmware cannot satisfy the reference driver's probe? If this firmware cannot pass the reference-board thermal-capability probe, I think the Lenovo binding should not use qcom,hamoa-crd-ec as a fallback. The fallback should be used only if the device is functionally compatible with the reference-board driver, not only because it uses the same EC chip. In that case, the binding changes in Daniel’s patch also need to be updated. -- Best Regards, Anvesh
