musb otg changes break booting on omaps

Looks like commit 84e250ffa76dddc1bad84e04248a27f442c25986 "musb: proper hookup to transceiver drivers" breaks booting on omaps if no transceiver is configured. Got any patches for that?

Regards,

Tony

Tony,

Is this on OMAP35x EVM? If so then the below patch should help.

and omap3x30-based hardware will most likely use twl4030-usb and in some cases (like evm) use the no-op trasceiver.
