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