| |
A USB connector should be a child node of the USB controller connector/usb-connector.txt. This patch adds an example of how to do this to the dwc3 binding descriptions.
It is necessary to declare a connector as a child-node of a USB controller for role-switching to work, so this example should be helpful to others implementing that.
