The conversion of the ARM Linux kernel over to the Device Tree as the mechanism to describe the hardware has been a significant change for ARM kernel developers. Nowadays, all developers porting the Linux kernel on new ARM platforms, either new SOCs or new boards, have to work with the Device Tree. Based on practical examples, this talk intends to provide a ""getting started guide"" for newcomers in the Device Tree world: what is the Device Tree? How is it written and compiled? How do the bootloader and kernel interact? How are Device Tree bindings written and documented? What are the best practices for writing Device Trees and their bindings?
