When one of the functions does not support super speed, the composite driver forces the gadget to high speed. But the speed is never configured in the cdns3 gadget driver. So configure the speed in cdns3_gadget_udc_start just like in the kernel.

Is this a patch picked from the kernel ? Is there a matching kernel commit ID ?
The commit 4df50f89f5 ("usb: composite: force gadget to be USB2 for HS only function") in u-boot, forces the gadget's max speed to high speed and had a mention in the commit description that the gadget's udc_start would configure itself in USB 2.0.
I checked the cdns3 gadget driver in kernel, and the cdns3_gadget_udc_start() configures speed. So this is not a patch picked directly from the kernel. I used kernel code for reference.
Thanks for clarification.
