Say Y here to enable external connector class (extcon) support.
This allows monitoring external connectors 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.
