| ST USB EHCI controller |
| |
| Required properties: |
| - compatible : must be "st,st-ehci-300x" |
| - reg : physical base addresses of the controller and length of memory mapped |
| region |
| - interrupts : one EHCI interrupt should be described here |
| - pinctrl-names : a pinctrl state named "default" must be defined |
| - pinctrl-0 : phandle referencing pin configuration of the USB controller |
| See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt |
| - 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 + reset specifier pairs to the powerdown and softreset lines |
| of 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: |
| |
| ehci1: usb@0xfe203e00 { |
| compatible = "st,st-ehci-300x"; |
| reg = <0xfe203e00 0x100>; |
| interrupts = <GIC_SPI 148 IRQ_TYPE_NONE>; |
| pinctrl-names = "default"; |
| pinctrl-0 = <&pinctrl_usb1>; |
| clocks = <&clk_s_a1_ls 0>; |
| phys = <&usb2_phy>; |
| phy-names = "usb"; |
| status = "okay"; |
| |
| resets = <&powerdown STIH416_USB1_POWERDOWN>, |
| <&softreset STIH416_USB1_SOFTRESET>; |
| reset-names = "power", "softreset"; |
| }; |
