+ 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.
