1 | ST USB EHCI controller |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible : must be "st,st-ehci-300x" | |
| 5 | - reg : physical base addresses of the controller and length of memory mapped | |
| 6 | region | |
| 7 | - interrupts : one EHCI interrupt should be described here | |
| 8 | - pinctrl-names : a pinctrl state named "default" must be defined | |
| 9 | - pinctrl-0 : phandle referencing pin configuration of the USB controller | |
| 07423fd8 | 10 | See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt |

11 | - clocks : phandle list of usb clocks |
| 12 | - clock-names : should be "ic" for interconnect clock and "clk48" | |
| 13 | See: Documentation/devicetree/bindings/clock/clock-bindings.txt | |
| 14 | ||
| 15 | - phys : phandle for the PHY device | |
| 16 | - phy-names : should be "usb" | |
| 17 | - resets : phandle + reset specifier pairs to the powerdown and softreset lines | |
| 18 | of the USB IP | |
| 19 | - reset-names : should be "power" and "softreset" | |
