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