> The QMP USB3-DP combo PHY stops the USB3 PIPE clock when a Type-C
> DisplayPort pin assignment gives it all four lanes for DisplayPort,
> while the controller can keep running its USB 2.0 port. The controller
> has to move to the UTMI clock before that happens, so it needs to know
> the Type-C mode. It does not route any signals itself.
>
> The Type-C class passes the mode only to graph nodes that have the
> "mode-switch" property, so allow it on the controller node through
> usb-switch.yaml. Orientation and retimer switching do not apply to the
> controller.
