Happy to see this on the list Jonathan, just some minor things on the

One day we should stop being surprised by this and drop the "Apparently"
from this comment ;)

It would be nice to see a
firmware-name = "qcom/sm8150/adsp.mbn";
here. Because if we ever end up pushing firmware to linux-firmware this
DTB would continue to work.
Use https://github.com/andersson/pil-squasher to get mbn files out of
the mdt+bXX files for your testing (or just rename/symlink the mdt to
mbn for now).
