Description:
The supported power roles. This attribute can be used to request
- power role swap on the port when the port supports USB Power
- Delivery. Swapping is supported as synchronous operation, so
- write(2) to the attribute will not return until the operation
- has finished. The attribute is notified about role changes so
- that poll(2) on the attribute wakes up. Change on the role will
- also generate uevent KOBJ_CHANGE. The current role is show in
