| 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. | |
