Kishon, any > hints? Extcon framework can be used to detect the connector status. So the PHY driver should register with the extcon framework if it has the capability to determine the connector status and the gadget driver should register with the extcon framework if it has to receive the connector status. I'm not sure if we should be adding these extcon APIs inside the PHY framework itself as all PHYs might not have the capability to detect the connector status.
