Improve the binding example by removing all the leading 0x to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
Converted using the following command:
find Documentation/devicetree/bindings -name "*.txt" -exec sed -i -e 's/([^ ])\@0x([0-9a-f])/$1\@$2/g' {} +

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@fe203e00 {
|
|
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";
|
|
|
|
resets = <&powerdown STIH416_USB1_POWERDOWN>,
|
|
<&softreset STIH416_USB1_SOFTRESET>;
|
|
reset-names = "power", "softreset";

};
