Device Tree

This page documents how to get started with Open Firmware's Device Tree on MIPS. It does not cover other device trees such as that of the ARC Firmware or klconfig.

Documentation

• OpenBIOS
• Documentation/devicetree in the kernel sourcecode.
• PNP Device IDs
• Sun's IEEE1275 Open Firmware site

Required Tools

The Device Tree Compiler used to generate Open Firmware style device trees images is contained in the Fedora and openSUSE dtc rpm.

MIPS Platforms with Device Tree support

PowerTV is the initial MIPS platform with Device Tree support. Work to convert further platforms to DT is in progress and there is a git tree (linux-dt.git gitweb) for this project.
