+Kernel driver cros_ec_hwmon
+===========================
+
+Supported chips:
+
+  * ChromeOS embedded controllers connected via LPC
+
+    Prefix: 'cros_ec'
+
+    Addresses scanned: -
+
+Author:
+
+  - Thomas Weißschuh <linux@weissschuh.net>
+
+Description
+-----------
+
+This driver implements support for hardware monitoring commands exposed by the
+ChromeOS embedded controller used in Chromebooks and other devices.
+
+The channel labels exposed via hwmon are retrieved from the EC itself.
+
+Fan and temperature readings are supported.
