  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.
