5Required properties:
6 - compatible: should be "ti,keystone-dwc3".
7 - #address-cells, #size-cells : should be '1' if the device has sub-nodes
8   with 'reg' property.
9 - reg : Address and length of the register set for the USB subsystem on
10   the SOC.
11 - interrupts : The irq number of this device that is used to interrupt the
12   MPU.
13 - ranges: allows valid 1:1 translation between child's address space and
14   parent's address space.

24The following are mandatory properties for Keystone 2 66AK2G SoCs only:
25
26- power-domains:	Should contain a phandle to a PM domain provider node
27			and an args specifier containing the USB device id
28			value. This property is as per the binding,
