Ah, that makes more sense now, thanks for the history lesson.

Converting the i2c core, and all drivers over to the kernel driver
model.  See include/linux/device.h for the structures and
Documentation/driver-model/* for lots of documentation.  Also, Pat
Mochel has written a lot of good documentation at:
	http://www.kernel.org/pub/linux/kernel/people/mochel/doc/lca/driver-model-lca2003.tar.gz

It basically involves hooking the drivers and core up to the rest of the
kernel, like I've already done.  All of the kernel's drivers are either
already converted to this model, or are in the process of being
converted.

For now, yes.

Not yet.  If you look at my original patch I sent to the list, I do hook
up the chip drivers to the driver core, but don't do much with them.  I
didn't include that portion in my patches to Linus as it needs some more
work to get everything working properly.

Does this help explain stuff?  I hope to have a more concrete set of
patches soon to show what I'm talking about (code is sometimes easier to
understand than documentation :)
