There is error:
 aarch64:  +   mt8512_bm1_emmc
+aarch64-linux-ld.bfd: drivers/usb/gadget/udc/built-in.o: in function
`usb_gadget_handle_interrupts':
+drivers/usb/gadget/udc/udc-uclass.c:56: undefined reference to
`dm_usb_gadget_handle_interrupts'

It seems that the gadget of mtu3 is not enabled, but the default mode is
gadget mode, not sure why not works.

I sent a patch to try to fix it:

configs: mt8512: enable device mode of mtu3 explicitly


Sorry for inconvenience
