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.

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.
