270 snps,rx-max-burst:
272 Max USB RX burst size. In host mode, this field specifies the
273 Maximum Bulk IN burst the DWC_usb3 core can perform. When the system
274 bus is slower than the USB, RX FIFO can overrun during a long burst.
275 You can program a smaller value to this field to limit the RX burst

301 Max USB TX burst size. When the system bus is slower than the USB,
302 TX FIFO can underrun during a long burst. Program a smaller value
