+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.
+
+
+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.
