MediaTek's XHCI implementation supports both USB 2.0 High Speed (HS) and USB 3.x Super Speed (SS). The block can also be synthesized with either HS-only capability or HS+SS capability. The SSUSB controller handles the device or gadget mode. Saying that SSUSB handles the HS portion is wrong. For example, on the MT8195, the first two instances support both HS and SS, while the latter two instances support only HS. Switch to a "ports" sub-node for describing USB connections. Port 1 is Super Speed if the controller is SS-capable, otherwise it is High Speed. Port 2 is High Speed if SS-capable. This port mapping scheme directly matches what the hardware returns in its capability registers.
