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:
