Happy to see this on the list Jonathan, just some minor things on the
remoteproc nodes below.

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).

	firmware-name = "qcom/sm8150/slpi.mbn";
