Unlike the Peach-Pit board, there is no parade edp to lvds bridge on the Pi. So drop it from device-tree

Tested on snow, pit, pi (display does not yet work on Pi).
Just to be clear, in your testing does the display not work on Pi? It seems to be ok here (with u-boot starting chainloaded from one of the KERN partitions)
That's right, not in U-Boot. I think this is because some GPIOs need to be enabled to turn on the backlight etc. Maybe you have an EC which turns these on automatically?
If current mainline is supposed to make the display work on Pi then I need to do some debugging. Please let me know.
It does work on my machine, so i was wondering if it's a setup difference. I'm using the chained u-boot method (iotw the standard chromeos u-boot in flash starts main-line u-boot from mmc/SD), which might well mean that the GPIOs you're referring to are still turned on by the first u-boot (which it has to do to show me the unverified boot warning screen)?
Yes that's right. Maybe Akshay / Ajay have ideas, or otherwise I can add this. I think it is two GPIOs, but it might be TPSCHROME also.
Now, I have added support for peach_pi display in u-boot. Kindly check the patches.
