yes, you already told we thet the BD71828 drivers are compatible with
the BD71879 and I am using the latter. 
But that at least should be commented somewhere, so that
people do not raise questions, like: Do I have some strange board revision,
etc?
The most terse form to comment it is a separate dt compatible so we are
prepare any "almost identical" surprises.
