+       tristate "External Connector Class (extcon) support"
+       help
+         Say Y here to enable external connector class (extcon) support.
+         This allows monitoring external connectors by userspace
+         via sysfs and uevent and supports external connectors with
+         multiple states; i.e., an extcon that may have multiple
+         cables attached. For example, an external connector of a device
+         may be used to connect an HDMI cable and a AC adaptor, and to
+         host USB ports. Many of 30-pin connectors including PDMI are
+         also good examples.
