We shouldn't have created these file links in the first place. I'd rather have something like this in our tree: arch/arm64/boot/dts/include/arm -> ../../../../arm/boot/dts arch/arm64/boot/dts/include/arm64 -> ../.. arch/arm/boot/dts/include/arm64 -> ../../../../arm64/boot/dts arch/arm/boot/dts/include/arm -> ../.. That way you can include by using <arm/bcm2835-rpi.dtsi> instead. You'll populate another (or the same) directory with links as appropriate in your out-of-tree version of the DT contents. No more symlinked files, and still a clear way of showing that you're referencing contents out of the other architecture. Considerably cleaner, isn't it? -Olof

The ../../../arm... style cross-references added by commit 9d56c22a7861 ("ARM: bcm2835: Add devicetree for the Raspberry Pi 3.") do not work in the context of the split device-tree repository[0] (where the directory structure differs). As with commit 8ee57b8182c4 ("ARM64: dts: vexpress: Use a symlink to vexpress-v2m-rs1.dtsi from arch=arm") use symlinks instead.
