During the last few years, Device Trees (DT) became the preferred method in the Linux kernel to express the relationships between the various hardware components in a computer system in an OS-agnostic way. In an ideal world, all device drivers, and SoC and board support code use DT, with perfect and stable DT bindings. In reality, developers are confronted with a mix of new pure-DT, existing DT-aware, and legacy DT-hostile components.
Moreover, they want to backport new drivers and board support to one of the various long term stable trees like LTSI, which may not offer the same level of DT support as the fast moving mainline kernel. In this presentation, Geert will address challenges and offer best practices for a smooth transition from board files and platform devices via DT-aware systems to pure-DT systems, keeping in mind compatibility with long term stable trees.
