1 ST USB OHCI controller
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

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";
