Yes, I can imagine what a mess it would become it we had one driver for every panel out there which sole purpose would be to define power sequences over more generic drivers. That reassures me about the usefulness of this work. Another (small) benefit of power sequences over specific drivers is that being defined in the DT, they would allow an old kernel to operate a newer device if the base driver is the same.
