description:
  The STMicroelectronics USB Open Host Controller Interface (OHCI)
  compliant USB host controller found in ST platforms. The controller
  provides full- and low-speed USB host functionality and interfaces
  with an external USB PHY. It requires dedicated clock, reset, and
  interrupt resources for proper operation.
