* For NVIDIA Driver Development Kit (NvDDK) clients, USB ULPI device
* means a USB controller connected to a ULPI interface that has an
* external phy. This API allows NvDDK clients to open the USB ULPI device by
* setting the ODM specific clocks to ULPI controller or external phy, so that USB ULPI
* device can be used.
