    1 ST USB EHCI controller
    2 
    3 Required properties:
    4  - compatible           : must be "st,st-ehci-300x"
    5  - reg                  : physical base addresses of the controller and length of memory mapped
    6                           region
    7  - interrupts           : one EHCI interrupt should be described here
    8  - pinctrl-names        : a pinctrl state named "default" must be defined
    9  - pinctrl-0            : phandle referencing pin configuration of the USB controller
   10 See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
   11  - clocks               : phandle list of usb clocks
   12  - clock-names          : should be "ic" for interconnect clock and "clk48"
   13 See: Documentation/devicetree/bindings/clock/clock-bindings.txt
   14 
   15  - phys                 : phandle for the PHY device
   16  - phy-names            : should be "usb"
   17  - resets               : phandle + reset specifier pairs to the powerdown and softreset lines
   18                           of the USB IP
   19  - reset-names          : should be "power" and "softreset"
   20 See: Documentation/devicetree/bindings/reset/st,stih407-powerdown.yaml
   21 See: Documentation/devicetree/bindings/reset/reset.txt
