+Kernel driver cgbc-hwmon
+========================
+
+Supported chips:
+
+ * Congatec Board Controller.
+
+   Prefix: 'cgbc-hwmon'
+
+Author: Thomas Richard <thomas.richard@bootlin.com>
+
+Description
+-----------
+
+This driver enables monitoring support for the Congatec Board Controller.
+This controller is embedded on the x86 SoMs of Congatec.
+
+Sysfs entries
+-------------
+
+The following sysfs entries list contains all sensors defined in the Board
+Controller. The available sensors in sysfs depend on the SoM and the
+system.
