There are two sensors, one for CPU, one for GPU.

Nit: my preference is to use words as the smallest increment, so this
would have a size of 8 instead of 6. 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.

So it should be 8 if we round it up to word boundary?
