The problem is due to an absent vendor prefix in the test kernel source tree
environment. As I said in the cover-letter the new vendor prefix will be added
in the framework of the next patchset:
https://lkml.org/lkml/2020/5/6/1047

Rob, please review that patchset first, merge in the corresponding patch from
there and test this binding out then.
