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,stih407-powerdown.yaml
