+ST USB OHCI controller
+
+Required properties:
+
+ - compatible : must be "st,st-ohci-300x"
+ - reg : physical base addresses of the controller and length of memory mapped
+ region
+ - interrupts : one OHCI controller interrupt should be described here
+ - clocks : phandle list of usb clocks
+ - clock-names : should be "ic" for interconnect clock and "clk48"
+See: Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+ - phys : phandle for the PHY device
+ - phy-names : should be "usb"
+
+ - resets : phandle to the powerdown and reset controller for the USB IP
+ - reset-names : should be "power" and "softreset".
+See: Documentation/devicetree/bindings/reset/st,sti-powerdown.txt
+See: Documentation/devicetree/bindings/reset/reset.txt
+
+Example:
+
+ ohci0: usb at 0xfe1ffc00 {
+ compatible = "st,st-ohci-300x";
+ reg = <0xfe1ffc00 0x100>;
+ interrupts = <GIC_SPI 149 IRQ_TYPE_NONE>;
+ clocks = <&clk_s_a1_ls 0>,
+ <&clockgen_b0 0>;
+ clock-names = "ic", "clk48";
+ phys = <&usb2_phy>;
+ phy-names = "usb";
+ status = "okay";
+
+ resets = <&powerdown STIH416_USB0_POWERDOWN>,
+ <&softreset STIH416_USB0_SOFTRESET>;
+ reset-names = "power", "softreset";
+ };
