Open Source Summit Europe + ELC Europe 2017

Previous installments of the Embedded Linux Conference had seen some talks about the infeasibility of establishing Devicetree as a stable ABI between Firmware and Kernel. While a lot of the arguments presented in those talks are valid, this one sets out to show that in fact it is possible to establish and keep a stable ABI. It is mainly a war story, presenting the lessons learned by the Pengutronix kernel and bootloader team while working with the NXP i.MX6 platform.

Attendees will learn what is needed to establish a stable Devicetree process and get to hear some best practices that have proven beneficial in the i.MX6 universe. By avoiding the pitfalls outlined in the talk, developers should be able to minimize incompatible changes to the DT ABI, improving the quality and user experience of the platforms they are working with.
