HI,
I think on the imx8mq platform we have a problem with the introduction of the clock driver. I tried to debug the problem that the pitx-imx8m board was not able to start for some time. I was wondering why the pitx-im8m doesn't work anymore although the imx8mq_evk is running.
So I switched to the imx8mq_evk for counter testing. As I already figured out in [1] also the imx8mq_evk is not able to start properly.
On the EVK I enabled the DEBUG_UART and see the outputs below. I suspect all imx8mq boards have this problem.
CONFIG_DEBUG_UART_BASE=0x30860000 # for uart1 CONFIG_DEBUG_UART_CLOCK=24000000

Could the maintainers of the other imx8mq boards please check if they can confirm this?
