You are declaring 8 bytes of calibration data but to my knowledge
it's
only 2 bytes per sensor, so 2 bytes for H3.
Am I missing something ?

Thanks,

Emmanuel you are right, it is 2 bytes per Sensor and should be 2
bytes for
H3, but the thermal calibration data field is on all chips 64 bit
wide - so
8 bytes. So I'm reading here the complete calibration data field.

Having one cell per channel would make more sense I guess.
Ok I will change this.

I have mentioned that this is impossible because of wrong
addressing caused by LE2BE in SID driver.

I know! But I would like to prepare patches for it, that they can be merged when this is fixed.
