0043 Description
0044 -----------
0045
0046 This driver implements support for Maxim MAX20710, MAX20730, MAX20734, and MAX20743
0047 Integrated, Step-Down Switching Regulators with PMBus support.
0048
0049 The driver is a client driver to the core PMBus driver.
0050 Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.

0052
0053 Usage Notes
0054 -----------
0055
0056 This driver does not auto-detect devices. You will have to instantiate the
0057 devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
0058 details.
