The STMicroelectronics USB Open Host Controller Interface (OHCI)
14
+
compliant USB host controller found in ST platforms. The controller
15
+
provides full- and low-speed USB host functionality and interfaces
16
+
with an external USB PHY. It requires dedicated clock, reset, and
17
+
interrupt resources for proper operation.
