  Federico Vaga authored Aug 13, 2020
```
It is important because we enter and exit the calibration part
whenever we probe()/remove() a device driver instance, or when we
set/unset the ADC pattern data. For the second it is important to have
the calibration identity in place.

We computed good values for the slope's tables with two aims:
- having proper integer math
- having the values in the same range as the calibration data

the offset user input is validated; in fa_dac_offset_get() there is a
paranoid check; if the offset is still out of range, then there is
something big and wrong somewhere.

drv: update calibration mechanism · 398f233d

Federico Vaga authored Aug 04, 2020

First we change change the values in the GAIN and OFFSET register,
then we apply the configuration by writing 1 in the CALIB_APPLY field.

The patch is more complex than just set one bit becuase it is ready to
implement the calibration thread that will compensate the GAIN factor
based on the current temperature.
