0004 help
0005 Say Y here to enable external connector class (extcon) support.
0006 This allows monitoring external connectors by userspace
0007 via sysfs and uevent and supports external connectors with
0008 multiple states; i.e., an extcon that may have multiple
0009 cables attached. For example, an external connector of a device
0010 may be used to connect an HDMI cable and a AC adaptor, and to
0011 host USB ports. Many of 30-pin connectors including PDMI are
0012 also good examples.
