I can, but wouldn't we then miss the more specific compatible strings in 
the DT ?

compatible = "waveshare,13.3inch-panel", "panel-dpi";
              ^^^^^^^^^^^^^^^^^^^^^^^^^^
              this ... would be removed. Do we want that ?

The other option would be to add the timings into panel-simple driver, 
then we wouldn't have to change the bindings at all. Maybe that would be 
preferable ?
