Commit 9ccd608070b6 ("arm64: dts: add device tree for ARM SMM-A53x2 on
LogicTile Express 20MG") added a new dts file to arch/arm64 which
included "../../../../arm/boot/dts/vexpress-v2m-rs1.dtsi", i.e. a
.dtsi supplied by arch/arm.

Unfortunately this causes some issues for the split device tree
repository[0], since things get moved around there. In that context
the new .dts ends up at src/arm64/arm/vexpress-v2f-1xv7-ca53x2.dts
while the include is at src/arm/vexpress-v2m-rs1.dtsi.

Hi Grant,

Do you think there is any chance of getting this into 4.2-rc$NEXT or shall
we wait until 4.3? I'm assuming this should go via the DT tree, but maybe
it should go via an ARM tree?

I was assuming this would go thru the arm-soc tree which is why I
acked it. It is getting a bit late for 4.2 at this point, but I guess
the standalone tree remains broken for these platforms until this is
done. Probably not such a big deal in grand scheme of things.

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/<arch>/*, at least if
there's expected to be contents in there.

We don't have include/linux/asm-<arch>/ 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?
