Most panels need information other than EDID. They typically have some
requirements regarding the power up sequence that aren't to be found
anywhere in EDID or detectable by some other mechanism. A decision was
therefore made a long time ago to require panels to be listed in DT with
a specific compatible string. That way all of these details can be
stashed away in drivers that know how to deal with these kinds of
details.
