I create gadget usb_f_fs driver and create gadget structure. it's successfully registered.
but UDC dwc3 not started its fail every time.
below showing error
root@imx8mp:/run/usb/config/usb_gadget/g1# echo 38100000.dwc3 > UDC

it's UDC not success fully bind with gadget attach code snap
dev_dbg(&udc->dev, "registering UDC driver [%s]\n",
driver->function);
udc->driver = driver;
udc->dev.driver = &driver->driver;
udc->gadget->dev.driver = &driver->driver;

ret = driver->bind(udc->gadget, driver);
if (ret)

goto err1;
