Yes, that's the thinking behind my approach of not touching existing code - I don't feel too bad about making new stuff depend on new features but for older stuff I'd rather leave it alone for now. Once we can manage to deliver the WFI states there would be a very useful win there so there's going to be a benefit to users from turning it on. > only..

Yeah, I don't really have access to too much of the shiny new stuff right now so I've not been able to take advantage of a lot of the stuff you guys are doing. My primary development platform is S3C6410 based at the minute. -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
