Indentation error I have rectified in my RFC v2.
Regarding below warnings

"Documentation/devicetree/bindings/usb/snps,dwc3.example.dts:86.27-89.15: Warning (unit_address_vs_reg): /example-2/usb@...00000/multiport/mport@1: node has a unit name, but no reg or ranges property"
  
Here the mport expects no "reg" or ranges" property as of now. Only thing that is mandated is either the USB-PHY phandles using "usb-phy" or the Generic PHY declaration using "phy" and "phy-names"
Can you please suggest to mask these warnings or do I need to add something else ?
