Ah, that would be the test driver not intended to be used in production
then...  That shouldn't be a blocker for the DT binding, and if there's
a different compatible string for this application then we can either
make the userspace consumer do something different based on that
compatible string or have a new driver which does something more
sensible and perhaps has a better userspace ABI.  Either way so long as
we can tell the thing being described is a BMC output from the DT
binding I think we can leave it up to the OS to do something constructive
with that rather than trying to control the specific behaviour in the
binding.
