862343c4ea adt7473: check inputs from sysfs writes 
Implement correct range checking for adt7470 to prevent userland from
writing impossible values into the chip, and cap out-of-range values per
standard hwmon conventions.

Implement correct rounding of input values per standard hwmon conventions.

be821b78af hwmon: (adt7473) Fix voltage conversion routines 
Fix voltage conversion routines. Based on an earlier patch from
Paulius Zaleckas.

According to the datasheet voltage is scaled with resistors and
value 192 is nominal voltage. 0 is 0V.

9d3e19afd3 hwmon: (adt7473) Remove unused defines 
All the *_MAX_ADDR defines are never used, so remove them. The number
of registers of each type is already expressed by the *_COUNT defines.

eea54766c6 hwmon: (adt7473) Convert to a new-style i2c driver 
The new-style adt7473 driver implements the optional detect() callback
to cover the use cases of the legacy driver.

ed4ec814e4 hwmon: (adt7473) Initialize max_duty_at_overheat before use 
data->max_duty_at_overheat is not updated in adt7473_update_device,
so it might be used before it is initialized (if the user reads from
sysfs file max_duty_at_crit before writing to it.)
