description:
  Texas Instruments glue layer for Synopsys DesignWare USB3 (DWC3)
  controller on OMAP and AM43xx SoCs. Manages SoC-specific integration
  including register mapping, interrupt routing, UTMI/PIPE interface mode
  selection (HW/SW), and child DWC3 core instantiation via address space
  translation. Supports both legacy single-instance and multi-instance
  (numbered) configurations.
