0001 ST USB OHCI controller
0002
0003 Required properties:
0004
0005 - compatible : must be "st,st-ohci-300x"
0006 - reg : physical base addresses of the controller and length of memory mapped
0007 region
0008 - interrupts : one OHCI controller interrupt should be described here
0009 - clocks : phandle list of usb clocks
0010 - clock-names : should be "ic" for interconnect clock and "clk48"
0011 See: Documentation/devicetree/bindings/clock/clock-bindings.txt
0012
0013 - phys : phandle for the PHY device
0014 - phy-names : should be "usb"
0015
0016 - resets : phandle to the powerdown and reset controller for the USB IP
0017 - reset-names : should be "power" and "softreset".
0018 See: Documentation/devicetree/bindings/reset/st,stih407-powerdown.yaml
