I'm cc:d in the far tail of a thread, so I'll just comment here instead of further up: I'm not a fan at all of creating kernel/dts//*, at least if there's expected to be contents in there. We don't have include/linux/asm-/ in the common tree either. Let's not create that for dts. So, while I'm all for a prefix-based sharing of DTSI files, I don't want them to go in a common kernel/dts directory. Besides sharing some snippets between arm and arm64, what else is expected to need to go into such a shared location today? -Olof
