Yes. I could find the below excerpts from [1]: "The compatibility rules say that new kernels must work with older device trees. If changes are required, they should be put into new properties; the old ones can then be deprecated but not removed. New properties should be optional, so that device trees lacking those properties continue to work. The device tree developers will provide a set of guidelines for the creation of future-proof bindings." -- viresh [1] http://lwn.net/Articles/572114/ -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
