Would be nice if you could use the SPDX thingy for the license.

I'm going to leave this alone. I definitely started this driver by
copy-pasting the panel-simple.c file and it still shares a lot of
lines of code with that driver. It feels like that qualifies for the
"substantial portions of the Software" portion which tells me to
retain the license. I also kept Thierry as the author since, again,
it's really a splitting of the existing driver and not the creation of
a new driver. In fact, if I were to assign a new author/license to
panel-edp, one could also make the argument that I should assign a new
author/license to panel-simple. panel-simple got ~50% of the old
panels and panel-edp got the other ~50% of the old panels plus a
search-and-replace of "simple" for "edp" and some code deletion. I
don't think search-and-replace name change nor code deletion is
justification for claiming authorship. ;-)

If Thierry wants to chime in and say that I should put down a
different license for either of the two files, though, I'd be glad to
change it.
