+Description
+-----------
+
+This driver supports the MAX16508 VR13 Dual-Output Voltage Regulator
+as well as the MAX16601 VR13.HC Dual-Output Voltage Regulator chipsets.
+
+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.
+
+
+Platform data support
+---------------------
+
+The driver supports standard PMBus driver platform data.
+
+
