# What is a Linux Device Tree?

The Device Tree (DT) is a data structure and language, constructed to
interface between an operating system and hardware, without needing hardcoded
details of the machine.

## Data Model

Linux uses Device Tree data for three major purposes:
- platform identification
- runtime configuration
- device population
