+               controller.
+ - #address-cells, #size-cells : should be '1' if the device has sub-nodes

+ - 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 Exynos dwc3 glue.
