TI Keystone Soc USB Controller
DWC3 GLUE
Required properties:
- compatible: should be "ti,keystone-dwc3".
- #address-cells, #size-cells : should be '1' if the device has sub-nodes
with 'reg' property.
- reg : Address and length of the register set for the USB subsystem on
the SOC.
- interrupts : The irq number of this device that is used to interrupt the
MPU.
- ranges: allows valid 1:1 translation between child's address space and
parent's address space.
- clocks: Clock IDs array as required by the controller.
- clock-names: names of clocks correseponding to IDs in the clock property.
Sub-nodes:
The dwc3 core should be added as subnode to Keystone DWC3 glue.
- dwc3 :
The binding details of dwc3 can be found in:
Documentation/devicetree/bindings/usb/dwc3.txt
Example:
usb: usb@2680000 {
compatible = "ti,keystone-dwc3";
#address-cells = <1>;
#size-cells = <1>;
reg = <0x2680000 0x10000>;
clocks = <&clkusb>;
clock-names = "usb";
interrupts = <GIC_SPI 393 IRQ_TYPE_EDGE_RISING>;
ranges;
status = "disabled";
dwc3@2690000 {
compatible = "synopsys,dwc3";
reg = <0x2690000 0x70000>;
interrupts = <GIC_SPI 393 IRQ_TYPE_EDGE_RISING>;
usb-phy = <&usb_phy>, <&usb_phy>;
};
};
