Binary version of EDID
Decoded EDID
Many tools exist which can decode EDID.
On Ubuntu you can use edid-decode.
The ouput is below...

Human Readable version of EDID

Translated to devicetree
WIP
At the we use a samsung display with same resolution and similar timings which works.
But to optimize the devicetree someone has to decode EDID to panel-timings
