Embedded Linux Conference + Android Builders Summit

Embedded and mobile devices are very important targets of Linux kernel development. To accommodate the growing number of systems supported and their diversity, Device Tree has been adopted by Linux kernel community as the method to describe all the hardware components of such systems. This proven solution has been working well for PowerPC systems for years, but it is not free from issues. Existing tools do not provide any means to validate device trees against defined Device Tree bindings, leaving any error detection to maintainers' eyes. In this presentation, Tomasz will explain the problem of missing device tree validation and introduce a validation solution that he has been working on in cooperation with rest of Linux kernel community.
