With CONFIG_USB_ULPI=y, CONFIG_USB<=m, CONFIG_PCI=n and CONFIG_USB_OTG_UTILS=n, which is the default used for mx31moboard, the build for all mx3 platforms fails because drivers/usb/otg/ulpi.c where otg_ulpi_create is defined is not compiled. Build error: arch/arm/mach-mx3/built-in.o: In function `mxc_board_init': kzmarm11.c:(.init.text+0x73c): undefined reference to `otg_ulpi_create' kzmarm11.c:(.init.text+0x1020): undefined reference to `otg_ulpi_create' This isn't a strong dependency as drivers/usb/otg/ulpi.c doesn't use functions defined in drivers/usb/otg/otg.o and is only needed to get ulpi.o linked into the kernel image.

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.
