-Amlogic Meson GX DWC3 USB SoC controller
-
-Required properties:
-- compatible:  depending on the SoC this should contain one of:
-                       * amlogic,meson-axg-dwc3
-                       * amlogic,meson-gxl-dwc3
-- clocks:      a handle for the "USB general" clock
-- clock-names: must be "usb_general"
-- resets:      a handle for the shared "USB OTG" reset line
-- reset-names: must be "usb_otg"
-
-Required child node:
-A child node must exist to represent the core DWC3 IP block. The name of
-the node is not important. The content of the node is defined in dwc3.txt.
-
-PHY documentation is provided in the following places:
-- Documentation/devicetree/bindings/phy/meson-gxl-usb2-phy.txt
-- Documentation/devicetree/bindings/phy/meson-gxl-usb3-phy.txt
