This driver implements PHY initialization, clock management, ULPI IO ops and simple OTG state machine to kick host/peripheral based on Id/VBUS line status. VBUS/Id lines are tied to a reference voltage on some boards. Hence provide debugfs interface to select host/peripheral mode.

If you say yes here you get support for the Philips ISP1301
|
|
USB-On-The-Go transceiver working with the OMAP OTG controller.
|
|
The ISP1301 is a full speed USB transceiver which is used in
|
|
products including H2, H3, and H4 development boards for Texas
|
|
Instruments OMAP processors.
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called isp1301_omap.
