I'm not talking about phonet, I replied to your comment regarding
USB_GADGET_MUSB_HDRC. For me USB_GADGET_MUSB_HDRC=n USB_G_NOKIA=y
doesn't work, but the Kconfig allows it.

Ok, I'll make it: depends on (NOP_USB_XCEIV || TWL4030_USB)

BTW, if you want to try this:
./scripts/kconfig/conf --defconfig=usb_defconfig arch/arm/Kconfig

usb_defconfig:
CONFIG_ARCH_OMAP=y
CONFIG_EXPERIMENTAL=y
CONFIG_NET=y
CONFIG_PHONET=y

CONFIG_USB=y
CONFIG_USB_GADGET=y
CONFIG_USB_MUSB_OTG=y
CONFIG_USB_MUSB_HDRC=y
CONFIG_USB_G_NOKIA=y

# TODO USB_MUSB_OTG should select this
CONFIG_USB_GADGET_MUSB_HDRC=y

I expect TWL4030_USB and USB_OTG to be automatically selected.
