Since Linux 3.x, device tree is introduced as a data structure and language to describe
hardware configuration. It is a system-readable description of hardware settings so that
the operating system doesn’t have to hard code details of the machine.
A device tree is primarily represented in the following forms.
Device Tree Compiler (DTC): The tool used to compile device tree
into system-readable binaries.
Device Tree Source (DTS): The human-readable device tree
description file. You can locate the target parameters and modify hardware
configuration in this file.
Device Tree Source Information (DTSI): The human-readable header
file which you can include in device tree description. You can locate the target
parameters and modify hardware configuration in this file.
Device Tree Blob (DTB): The system-readable device tree binary blob
files which is burned in system for execution.
The following diagram shows the relationship (workflow) of the above forms. Figure 1. Device Tree Workflow
