[PATCH] ARM: dts: Add devicetree for the Raspberry Pi 3, for arm32 (v4)

[PATCH] ARM: dts: Add devicetree for the Raspberry Pi 3, for arm32 (v4)

[Eric Anholt]

Raspbian and Fedora have decided to support the Pi3 in 32-bit mode for
now, so it's useful to be able to test that mode on an upstream
kernel.  It's also been useful for me to use the same board for 32-bit
and 64-bit development.

v1: Gerd's patch that put the ../../../arm64/... link in the Makefile
v2: Michael's patch that #included from ../../../arm64/... in a new
    bcm2837-rpi-3-b.dts.
v3: Mine, using symlinks to make sure that we don't break the split DT
    tree.
v4: Rely on the new include/arm64 symlink.

Assuming positive review feedback, I assume it would be acceptable to
merge the shared/dt-symlinks branch in a PR of my own for the 32-bit
DT branch?

Either that, or I can take it directly through devicetree/next whichever
you prefer. We have not gotten feedback on whether this looks acceptable
or not though...

I would love if you could pull this patch, but it does require
shared/dt-symlinks.

Building straight out of (and into) the include dir is a little odd here.

A tiny wrapper *.dtb in this dir, that just includes a shared dts/dtsi
would be a lot nicer.

If you do that, we can still pick it up for 4.12.
