+Kernel driver acbel-fsg032
+==========================
+
+Supported chips:
+
+  * ACBEL FSG032-00xG power supply.
+
+Author: Lakshmi Yadlapati <lakshmiy@us.ibm.com>
+
+Description
+-----------
+
+This driver supports ACBEL FSG032-00xG Power Supply. This driver
+is a client to the core PMBus driver.
+
+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.
+
+Sysfs entries
+-------------
+
+The following attributes are supported:
