    1 ST USB OHCI controller
    2 
    3 Required properties:
    4 
    5  - compatible           : must be "st,st-ohci-300x"
    6  - reg                  : physical base addresses of the controller and length of memory mapped
    7                           region
    8  - interrupts           : one OHCI controller interrupt should be described here
    9  - clocks               : phandle list of usb clocks
   10  - clock-names          : should be "ic" for interconnect clock and "clk48"
   11 See: Documentation/devicetree/bindings/clock/clock-bindings.txt
   12 
   13  - phys                 : phandle for the PHY device
   14  - phy-names            : should be "usb"
   15 
   16  - resets               : phandle to the powerdown and reset controller for the USB IP
   17  - reset-names          : should be "power" and "softreset".
   18 See: Documentation/devicetree/bindings/reset/st,stih407-powerdown.yaml
