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.
Thierry, since you're most familiar with display support and IIRC have worked on this in U-Boot too, perhaps you could review this series? Let me know if you need me to forward the emails to you.
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.
Which boards in particular? If this is just other Tegra20 boards and simply because you haven't copied the relevant DTs from the kernel and/or made updates to any U-Boot defconfigs and/or config headers, can't you do that mechanically too? Sure you'll need other people to test boards you don't have, but IIUC the source changes are mechanical. If it's non-Tegra20 boards, can you expand on the cause of the breakage?
