-----------
|
||
|
|
|
||
|
|
This driver implements support for Maxim MAX20730, MAX20734, and MAX20743
|
||
|
|
Integrated, Step-Down Switching Regulators with PMBus support.
|
||
|
|
|
||
|
|
The driver is a client driver to the core PMBus driver.
|
||
|
|
Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.

Usage Notes
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This driver does not auto-detect devices. You will have to instantiate the
|
||
|
|
devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
|
||
|
|
details.
