There have been more than a few spirited discussions on the topic of device trees (described here) over the past few years, and we can probably expect a few more at this year’s Device Tree microconference. The main focus is on programs, scripts, techniques, and core support to help create correct device trees, validate existing device trees, and support troubleshooting of incorrect device trees, drivers, and subsystems. Within that area of focus, topics span the range from inspection to verification/validation to bindings to documentation. This microconference will also examine the impact of overlays, including boot-time and runtime updates to device trees.
