Since ARM started to use devicetrees, their impact on various subsystems in the kernel has been increasing significantly. Because they became the de-facto standard, everybody wants them soon. Because they need a ton of conversions and adaptions, a lot of questions are still unresolved. This carries potential for conflicts.Wolfram has dealt with devicetrees already on PowerPC and still does on ARM. Additionally, he co-maintains the I2C subsystem which is affected by devicetree conversions, too. Knowing both sides, as developer and as maintainer, he will talk about stumbling blocks experienced so far, e.g. typical pitfalls when inveting bindings or the high pace. A number of examples will be given with suggestions how to avoid common mistakes as well as confronting the audience with open questions to get a better idea of the underlying problems and what is still needed.
