2 tristate "External Connector Class (extcon) support"
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.
