[PATCH] ARM: dts: Add devicetree for the Raspberry Pi 3, for arm32 (v5)

[PATCH] ARM: dts: Add devicetree for the Raspberry Pi 3, for arm32 (v5)

[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.

Sounds like this should be
../arm64/boot/dts/broadcom/bcm2837-rpi-3.b.dts are reported by the
kbuild test robot?

Looks like a typo in the dts filename and in the include ( dot instead
of dash ).

Sorry about that, everyone.  I remember doing builds of the patch, but
maybe things succeeded because there was already a .dtb present in my
tree or something.
