1ST USB OHCI controller 2 3Required 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" 11See: 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". 18See: Documentation/devicetree/bindings/reset/st,sti-powerdown.txt 19See: Documentation/devicetree/bindings/reset/reset.txt 20 21Example: 22 23 ohci0: usb@0xfe1ffc00 { 24 compatible = "st,st-ohci-300x"; 25 reg = <0xfe1ffc00 0x100>; 26 interrupts = <GIC_SPI 149 IRQ_TYPE_NONE>; 27 clocks = <&clk_s_a1_ls 0>, 28 <&clockgen_b0 0>; 29 clock-names = "ic", "clk48"; 30 phys = <&usb2_phy>; 31 phy-names = "usb"; 32 status = "okay"; 33 34 resets = <&powerdown STIH416_USB0_POWERDOWN>, 35 <&softreset STIH416_USB0_SOFTRESET>; 36 reset-names = "power", "softreset"; 37 }; 38
