     13description: |
     14  The Amlogic G12A embeds a DWC3 USB IP Core configured for USB2 and USB3
     15  in host-only mode, and a DWC2 IP Core configured for USB2 peripheral mode
     16  only.
     17
     18  A glue connects the DWC3 core to USB2 PHYs and optionally to an USB3 PHY.
     19
     20  One of the USB2 PHYs can be re-routed in peripheral mode to a DWC2 USB IP.
     21
     22  The DWC3 Glue controls the PHY routing and power, an interrupt line is
     23  connected to the Glue to serve as OTG ID change detection.
     24
     25  The Amlogic A1 embeds a DWC3 USB IP Core configured for USB2 in
     26  host-only mode.
     27
     28  The Amlogic GXL, GXM & AXG SoCs doesn't embed an USB3 PHY.
