I am getting a few errors on the i.MX8MN:

[    7.854193] imx-cpufreq-dt: probe of imx-cpufreq-dt failed with error -2

I was curious to know if anyone else is seeing similar errors.  I
already submitted a proposed fix for a DMA timeout (not shown here)
which matched work already done on i.MX8MQ and i.MX8MM.

I am not seeing huge differences between 8MM and 8MN in the nodes
which address the timer, caam or imx-cpufreq-dt.

If anyone has any suggestions, I'd love to try them.

I don't have access to a i.MX8MN board at the moment, but I am
wondering if the errors could be AT-F related.

Which version do you use? Could you try
https://source.codeaurora.org/external/imx/imx-atf/log/?h=imx_5.4.3_2.0.0
?
