Ok, if it is not a samsung panel, then maybe panel-edp will work.  So
far all the OLEDs I've seen are samsung, and they have a different
power sequence (hence needing different panel driver)

So far, it is just the samsung panel vs everyone else, where we would
need different dtb.  Maybe we come up with other variants, we'll see
as time goes on, but it shouldn't need to be for _every_ variant.

For the panel, edid-decode will tell us the panel name/vendor, ie.
something like:

cat /sys/devices/platform/soc@...e00000.display-subsystem/ae01000.display-controller/drm/card0/card0-eDP-1/edid
| edid-decode
