8 title: Amlogic Meson G12A DWC3 USB SoC Controller Glue
11 - Neil Armstrong <narmstrong@baylibre.com>
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
18 A glue connects the DWC3 core to USB2 PHYs and optionally to an USB3 PHY.
20 One of the USB2 PHYs can be re-routed in peripheral mode to a DWC2 USB IP.
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.
25 The Amlogic A1 embeds a DWC3 USB IP Core configured for USB2 in
28 The Amlogic GXL, GXM & AXG SoCs doesn't embed an USB3 PHY.
