title: Texas Instruments OMAP MUSB USB OTG Controller

maintainers:
  - Felipe Balbi <balbi@ti.com>

description:
  Texas Instruments glue layer for the Mentor Graphics MUSB OTG controller.
  Handles SoC-specific integration including PHY interface bridging(ULPI/
  UTMI), interrupt aggregation, DMA engine coordination (internal/
  external), VBUS/session control via control module mailbox, and
  clock/reset management. Provides fixed hardware configuration parameters
  to the generic MUSB core driver.
