Hi, I'm upgrading from 2.6.36 to 2.6.37 on a MPC8313 ERDB-like board. On the new kernel, it seems like the USB gadget driver (fsl_usb2_udc) is never initialized, so USB no longer works.
Adding some printks to the code shows that udc_init() is being run, which calls platform_driver_probe(). However, fsl_udc_probe() is never actually called afterward. As a result, 'udc_controller' is left NULL, and the subsequent call to usb_gadget_probe_driver() returns -ENODEV. I'm not familiar with the USB driver model, and tracing backward through the call chains didn't reveal much, so I was hoping someone here would have a better idea what could've changed between 2.6.36 and 2.6.37 that broke fsl_udc_core/fsl_usb2_udc.
