+Kernel driver MAX20754
+======================
+
+Supported chips:
+
+  * Maxim MAX20754
+
+    Prefix: 'max20754'
+
+    Addresses scanned: -
+
+    Datasheet: https://datasheets.maximintegrated.com/en/ds/MAX20754.pdf
+    Application Note: 
+
+Author: Atif Emre Ofluoglu  <Atif.Ofluoglu@xxxxxxxxxx>
+
+
+Description
+-----------
+
+This driver supports MAX20754 Dual-Output, Configurable Multiphase 
+Power-Supply Controller with PMBus Interface and Internal Buck Converter.
+
+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.
+
+
+Sysfs entries
+-------------
+
+The following attributes are supported.
