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:
https://github.com/cdleonard/arm-trusted-firmware/commits/imx_2.0.y_busfreq
