How can we change the speed of 16550 FPGA uart driver?

Linux Kernel

Hi,
We are using Arria10 SoC , with linux kernel 4.1.22.
We want to use 16550 FPGA UART with the speed 5M Hz. How can we change the speed in uart driver. As of now we are using “drivers/tty/serial/of_serial.c” as a driver.

Thanks and Regards,
