No, there is no automated tool, because it is not possible to do that
automatically. The device drivers used by your board must have a Device
Tree binding, and writing the Device Tree source cannot directly be
done from the C board file. It requires human knowledge and
intervention.

Could you be more specific about the platform you would look to convert
to the Device Tree? Where is the existing source code?

Best regards,

Thomas
