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