ASPM12160 is a quarter brick DC/DC Power Module. It is a high
power non-isolated converter capable of delivering a fully
regulated 12V, with continuous power level of 1600W with peak
power at 2400W for a limited time. Uses PMBus Configuration.

Description
-----------
-This driver supports hardware monitoring for Maxim MAX34440 PMBus 6-Channel
-Power-Supply Manager, MAX34441 PMBus 5-Channel Power-Supply Manager
-and Intelligent Fan Controller, and MAX34446 PMBus Power-Supply Data Logger.
-It also supports the MAX34451, MAX34460, and MAX34461 PMBus Voltage Monitor &
-Sequencers. The MAX34451 supports monitoring voltage or current of 12 channels
-based on GIN pins. The MAX34460 supports 12 voltage channels, and the MAX34461
-supports 16 voltage channels.

+voltage channels, and the MAX34461 supports 16 voltage channels. The ADPM1260
+also monitors both input and output of voltage and current.
The driver is a client driver to the core PMBus driver. Please see
Documentation/hwmon/pmbus.rst for details on PMBus client drivers.

If you say yes here you get hardware monitoring support for Maxim
MAX34440, MAX34441, MAX34446, MAX34451, MAX34460, and MAX34461.
+ Other compatible includes ADPM12160.
This driver can also be built as a module. If so, the module will
be called max34440.
