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,sti-powerdown.txt | |
