b180d05084 hwmon: (adt7475) Add support for the ADT7473
Add support for the ADT7473 to the adt7475 driver, and mark the
adt7473 driver for removal. The ADT7473 and ADT7475 chips are almost
the same chip and essentially compatible, so there's no point in
having separate drivers for them.

52df6440a2 hwmon: Clean up detect functions
As kind is now hard-coded to -1, there is room for code clean-ups.

8f8c1fb0c8 adt74{62, 70, 73}: Use DIV_ROUND_CLOSEST for rounded division
Modify some hwmon drivers to use DIV_ROUND_CLOSEST instead of bloating
source with (naughty) macros.

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.

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.

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.)
