Embedded Linux Conference 2014
San Jose, Ca

Thomas Petazzoni

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?
