hwmon: (pmbus/max34440): add support adpm12200
ADPM12200 is a quarter brick DC/DC Power Module. It is a high power non-isolated converter capable of delivering regulated 12V with continuous power level of 2000W. Uses PMBus.

If you say yes here you get hardware monitoring support for Maxim
|
||||
MAX34440, MAX34441, MAX34446, MAX34451, MAX34460, and MAX34461.
|

Other compatible are ADPM12160, and ADPM12200.
|

This driver can also be built as a module. If so, the module will
|

be called max34440.
