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