Yes! The topology is different (serving different IP blocks) but no 
functional code changes are required between 8mm 8mn 8mq.

I already wrote the code and tested it but didn't post because I want to 
get the core parts in first. I periodically push my "full" 
work-in-progress to github:

https://github.com/cdleonard/linux/commits/next_imx8mm_busfreq

You need out-of-tree ATF changes or devfreq probe will fail:
