Are all 12 sensors used ? I see that in a later patch "arm64: dts: qcom: sdm630: Add thermal-zones configuration" only 9 are used.

Hi,

if I recall correctly, they all give output but not all of the mappings were documented in the downstream sources and we have no documentation whatsoever :(

Right. In that case, why not change #qcom,sensors to 9 and add rest of the sensors if and when needed ?
