   1 TI Keystone Soc USB Controller
   2
   3 DWC3 GLUE
   4
   5 Required 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.
  15  - clocks: Clock IDs array as required by the controller.
  16  - clock-names: names of clocks correseponding to IDs in the clock property.

  18 Sub-nodes:
  19 The dwc3 core should be added as subnode to Keystone DWC3 glue.
  20 - dwc3 :
  21    The binding details of dwc3 can be found in:
