| help |
| Say Y here to enable external connector class (extcon) support. |
| This allows monitoring external connectors by userspace |
| via sysfs and uevent 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. |
