While touching the bindings file, can I convince you to convert it to
meta-schema format (.yaml)?

It would be nice if there was a "description" for each pair of
compatible that identified the actual panel.
In your case "Okaya RH128128T 1.44" 128x128 TFT display"
It can be looked up in git history - but better to have it in the
binding file.
