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.
Can't that be handled by placing the new code under an ifdef, so the source code can support either the old or the new scheme, then each board can be converted over and the ifdef flipped in its per-board config file, then the ifdef removed once all boards are converted?
To some extent, although there is the common tegra20.dtsi and lots of common code. It was more pain than I was willing to bear.
Another option is to eventually disable LCD for boards where the maintainers don't respond.
