This is the driver for the USB Type C cable detection mechanism built into the ChromeOS Embedded Controller on systems that have USB Type-C ports. At present, this allows for the presence of display out, but in future, it may also be used to notify host and device type cables and the presence of power.

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.
