This was taken from commit b48c54e2 at:
git://git.kernel.org/pub/scm/linux/kernel/git/olof/tegra.git

config.mk is updated to provide this file to boards through the
built-in mechanism:

/include/ ARCH_CPU_DTS

This is slightly out-of-date now; in next-20120118, that node's
compatible flag is nvidia,tegra20-i2c-dvc. The HW register layout is
somewhat different for this I2C controller, and the different compatible
flag is how the driver this.

Still, you can always apply that fix in a later patch before you add I2C
support.

This series was original submitted 24 November, so of course things
change. The changes you mention relate to I2C and I think I picked
these up in the later I2C patches.

As I said, as long as this is updated before the I2C support that relies
on it (as IIRC your I2C patch series did), that's fine.
