+ - #address-cells, #size-cells : should be '1' if the device has sub-nodes
+ with 'reg' property.
+ - reg : Address and length of the usb phy control register set.
+
+The main purpose of this PHY driver is to enable the USB PHY reference clock
+gate on the Keystone SOC for both the USB2 and USB3 PHY. Otherwise it is just
+an NOP PHY driver. Hence this node is referenced as both the usb2 and usb3
+phy node in the USB Glue layer driver node.

+TI Keystone Soc USB Controller

+DWC3 GLUE
+
+Required properties:
+ - compatible: should be "ti,keystone-dwc3".
+ - #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.
+ - 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 Keystone DWC3 glue.
+- dwc3 :
+ The binding details of dwc3 can be found in:
