hwmon: (pmbus/max34440) Add support for ADPM12160
ADPM12160 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.
|
||||
This driver supports multiple devices: 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; PMBus Voltage Monitor and Sequencers for MAX34451, MAX34460, and
|
||||
MAX34461; PMBus DC/DC Power Module ADPM12160. 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. 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.
