The Samsung ATNA45DC02 panel is an AMOLED eDP panel, similar to the
existing ATNA45AF01 and ATNA33XC20 panel but with a higher resolution.

This makes me wonder if we should define a cover compatible like
samsung,amoled-edp-panel.

Please follow what we decided in Stephan Gerhold's case and use a
fallback compatible. In other words: your patch seems to be based on
his v1 and not his v2.

I will bow to the wisdom of the DT folks, but my understanding is that
we shouldn't do that. The fallback compatible can just be the
compatible of the first panel that we supported that used the same
interface.
