Ah, that makes more sense now, thanks for the history lesson. > guess I missed something, exactly what are the "driver model changes"? 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. > I see a new adapter.dev.parent in the bus drivers, is that it? For now, yes. > Are there any changes affecting the chip drivers? I didn't see any. 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 :) thanks, greg k-h
