TI Keystone Soc USB Controller
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
- 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,
The dwc3 core should be added as subnode to Keystone DWC3 glue.
- dwc3 :
The binding details of dwc3 can be found in:
