I've just applied your patch in my for_3.7/dts_part2 branch.

I changed the subject to use "ARM: dts: " prefix seems it seems to be
the convention nowadays.

I removed as well the reference to Tony's tree, since that will become
irrelevant when it will be the commit changelog in the git tree in 2
years from now :-)

Thanks,
Benoit
