From my understanding MTK_THERMAL_V2 driver allwasy use extract and convert in version _v2. So we won't need to add the callbacks but could check in the code depending on .version which funtion to call. You patch set has some ordering issues. I think you should in a first patch rename function to _v1. Then in a second patch add actually add .version and _v2 and fix mt7622. The latter should also have a Fixes tag. Not sure if both patches as they both together actually fix mt7622 driver.

It is known that Mediatek owns two thermal system, which differs in the way of reading calibration data and converting temperature. MT8173, MT2701, MT2712 and MT8183 belongs to version 1 thermal system, and MT7622 belongs to version 2 thermal system. For platform compatibility, we add two sensor ops (extract and convert) to the thermal data structure. Each platform will register the sensor ops to the proper function implementation according to its version.
