Just in case I misunderstood,

You would prefer different SoC-specific compatible strings like
"sophgo,cv1800-thermal" "sophgo,sg2002-thermal" added to the driver,
and each thermal-sensor node contains two compatible strings, one
matches the SoC exactly and one is "sophgo,cv1800-thermal" just as a
fallback, right?
