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.
