Sync everything except the display panel, which will come in a future patch. One USB port is left disabled since we don't want to support it in U-Boot.
It would be useful to mention which version of Linux this DT content came from.
BTW, this series (at least this patch) seems to have a significant number of "git am" conflicts when I try to apply it to either v2016.01 or u-boot/master as of today. Consequently I can't apply it to test it. Which commit/branch is it based on?
See u-boot-dm/rkf-working, which has all the patches.
diff --git a/arch/arm/dts/tegra20-seaboard.dts b/arch/arm/dts/tegra20-seaboard.dts
pinmux@70000014 {pinctrl-names = "default";pinctrl-0 = <&state_default>;I agree that the DT content that's common between U-Boot's and Linux's copies of the DT files should be identical. However, I wonder if it makes sense to include nodes (and perhaps even properties) in U-Boot's DT that U-Boot doesn't use.
I can see the argument that keeping the files identical is easier to track and remove any differences.
However, I'd also argue that keeping the U-Boot DT files lean (i.e. only containing the nodes U-Boot uses) will allow easier determination of exactly what parts of the DT U-Boot uses, and hence perhaps highlight any parts that might still need conversion.
Indeed. I'm leaning towards including everything since it is simple. On tegra we don't use pinctrl so that is a waste, but it's not that huge.
