| 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. |
