The QMP USB3/DP Combo PHY can work in 3 modes: - DisplayPort Only - USB3 Only - USB3 + DisplayPort Combo mode In order to switch between those modes, the PHY needs to receive Type-C events, allow marking to the phy with the mode-switch property in order to allow the PHY to Type-C events. Reference usb-switch.yaml as a simpler way to allow the mode-switch property instead of duplicating the property definition.
