A comment from the peanut gallery:

The old tee.rst starts out describing the userspace API (include/uapi/,
/dev/tee, etc.). Maybe this part should go into
Documentation/userspace-api/.

The rest of the document describes the internal kernel API (how to write
a TEE driver). And maybe this part should go into Documentation/driver-api/.

At least I think that kind of split is what the documentation is going
for in the long term, so if you're moving these files around anyway it
might make sense to do it right away.
