Device Tree (Devicetree)

Purpose

Guide agents through Linux device tree source (DTS): syntax, bindings, phandles, overlays, and how the kernel OF (Open Firmware) layer parses hardware description into platform_device instances.

When to Use

• Platform driver not probing — DT mismatch
• Adding a new board .dts or fragment overlay
• Understanding compatible, reg, interrupts, clocks properties
• Cross-checking hardware with skills/kernel-dev/platform-device-model

Workflow

1. DTS structure
