Description |
|
----------- |
|
|
|
This driver implements support for Maxim MAX20710, 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. |
