The original tegra20 display driver was written before Linux had device tree bindings for display. Since then Linux has developed a robust set of bindings covering various aspects of enabling a display.
This series moves closer to those bindings by using the panel and backlight as separate drivers. The device tree files for seaboard, ventana and harmony thereby become almost the same as Linux.
Unfortunately this breaks the other boards, which will need a similar sync. So I'm not sure how easy it will be to accept this series. Still, it seems worth sending it out in the hope that board maintainers can help. I have kept this series separate so that it can progress separately.
