   13 description: |
   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.
