Something I forgot to mention: doing it this way is beneficial for suspend/resume and is generally the modern way of doing a self-sufficient in-kernel driver.
The natural next step will be to extend this approach to Intel CPUs (there's nothing inherently AMD specific about it) - that is still work in progress and was not ready for this merge window.
Just in case someone is wondering.
Thanks,
