Rob, it might be worth keeping this in a separate branch in linux-next
so you can pull it out if it causes any issues. I've been using these
patches for quite a while now, but there's always opportunity for
surprises on architectures I don't use. I did just fix a bug when
building with O= a few days back, hence the V2 that I posted as patches.

----------------------------------------------------------------

This branch enhances the support for running dtc on device tree files.

A dedicated directory is created for header files that provide constants
for device-tree bindings.

The kbuild dependency script processor is enhanced to support processing
the dependency outputs from multiple separate commands at once.

The kbuild dtc rule is modified so that the C pre-processor is always
applied when compiling any device tree.

Some standard headers are created which define common constants for GPIO,
IRQ, and ARM GIC device tree bindings.

----------------------------------------------------------------

The following changes since commit 6dbe51c251a327e012439c4772097a13df43c5b8:

  Linux 3.9-rc1

No, you're on the hook to fix anything. :) My next branch is pulled by
Grant and is not rebased. Perhaps we should change that, but it's not
going to happen right away.

I just rebuilt my imx/dt branch based on this to avoid all those dts
files renaming.  So regardless of the path it goes to mainline, I will
need it as a dependency in arm-soc tree.
