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.
