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-bindings.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";
};
