Same goes for the A64 dts. AFAICT this doesn't impact the driver in any way.H6 has only 2 sensors, so it should be 4. That's my overlook, I'll change it to 4 for H6 and to 8 for A64.
No it's correct. There's 2 bytes reference temperature and 2x 2 byte values for individual sensor calibration constants. regards, o.
