| 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 |
| 19 | See: Documentation/devicetree/bindings/reset/reset.txt |

| 21 | Example: |
| 22 | |
| 23 | ohci0: usb@fe1ffc00 { |
| 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 | |
| 33 | resets = <&powerdown STIH416_USB0_POWERDOWN>, |
| 34 | <&softreset STIH416_USB0_SOFTRESET>; |
| 35 | reset-names = "power", "softreset"; |
| 36 | }; |
