| 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. |
