As I wrote in discussion about s6e3ha2, there is no edge version of
s6e3ha2, it is just different panel: s6e3hf2, or more precisely IC driver.

I think "samsung,s6e3hf2" should be then used, I guess it could be even
simpler to just add new compatible string to samsung,s6e3ha2.txt binding
with some comments, as these panels are of the same family.
