   I am using i.MX6ul  core processor,use uart2 in 230400Baud,sometimes get error imx-uart 21e8000.serial: Rx FIFO overrun.

   following dmesg, I found this error msg followed Bus freq set to 24000000  msg。So i guess when the data transmission  in UART ,this time the Bus freq reduced,then RX FIFO overrun.Could someone help me to fixed.
