-TI Keystone Soc USB Controller
-
-DWC3 GLUE
-
-Required properties:
- - compatible: should be
- "ti,keystone-dwc3" for Keystone 2 SoCs
- "ti,am654-dwc3" for AM654 SoC
- - #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.
-
-SoC-specific Required Properties:
-The following are mandatory properties for Keystone 2 66AK2HK, 66AK2L and 66AK2E
-SoCs only:
-
-- clocks: Clock ID for USB functional clock.
-- clock-names: Must be "usb".
-
-
-The following are mandatory properties for 66AK2G and AM654:
-
-- power-domains: Should contain a phandle to a PM domain provider node
- and an args specifier containing the USB device id
- value. This property is as per the binding,
- Documentation/devicetree/bindings/soc/ti/sci-pm-domain.txt
-
-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;
-
- dwc3@2690000 {
- compatible = "synopsys,dwc3";
- reg = <0x2690000 0x70000>;
- interrupts = <GIC_SPI 393 IRQ_TYPE_EDGE_RISING>;
- usb-phy = <&usb_phy>, <&usb_phy>;
- };
- };
