+Kernel driver acbel-crps
+=======================
+
+Supported chips:
+
+  * ACBEL Common Redundant Power Supply.
+  Supported models: FSG032-00xG
+
+Author: Lakshmi Yadlapati <lakshmiy@...ibm.com>
+
+Description
+-----------
+
+This driver supports ACBEL Common Redundant 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
+-------------
+
