This is in no way specific to the BeagleBones, there's plenty of other
boards out there with similar setups like the Raspberry Pi and its
derivatives.

This is the general case, there will be a substantial level of
compatibility between different base boards by virtue of the pinouts
being the same but obviously there will be some variation in the
specifics (and even where that exists it may not be enough to be visible
at the DT level for the most part).  That said there will doubtless be
some plug in modules that want to rely on the specifics of a given base
board rather than remain compatible with general users of the interface.
