Correct, right now none of the extra compatible strings are
documented in the binding file. E.g. "tpo,taal" is used by
omap4-sdp and in the example section of the DT bindings.

We don't know the Droid 4 panel vendor and/or model. For
N950 "nokia,himalaya" is used, which is obviously also
not the real vendor. But for N950 there is a good reason
to use a N950 specific compatible anyways, since some
pixels are covered by plastic.
Maybe this can just be handled when the bindings file is
converted to YAML?
