So I only looked at imx6qdl.dtsi where the clocks are different
clocks = < IMX6QDL_CLK_UART_IPG>,

With the clock driver enabled for the imx8mq, it was noticed that the
frequency used to calculate the baud rate is always taken from the root
clock of UART1. This can cause problems if UART1 is not used as console
and the settings are different from UART1. The result is that the console
output is
