[Verse 1] Map the silicon landscape, node by node we trace Every peripheral whispers its address space Compatible strings declare what drivers seek Memory ranges carved where registers speak The bootloader passes this electric blueprint down To kernels hungry for hardware they've found [Chorus] Device tree describes, device tree defines Compatible binds, memory aligns Properties flow in key-value pairs Hierarchy shows what each component shares DTS compiles to DTB binary form Hardware topology takes its shape and form [Verse 2] Root node spreads its branches wide and deep CPU clusters where instruction sets sleep GPIO controllers with their numbered pins I2C masters where serial talk begins Status disabled means the hardware waits Interrupt parents route their numbered gates [Chorus] Device tree describes, device tree defines Compatible binds, memory aligns Properties flow in key-value pairs Hierarchy shows what each component shares DTS compiles to DTB binary form Hardware topology takes its shape and form [Bridge] Ampersand labels point to distant nodes Phandles weave the interconnection codes Clock frequencies pulse in hertz arrays Voltage regulators guard their power ways Overlays patch the structure on demand While chosen nodes help kernels understand [Verse 3] Board-specific flavors override the base SoC templates set the common pace Driver matching reads the compatible line Probe functions wake when signatures align From ARM boot loaders to embedded cores Device trees unlock each platform's doors [Chorus] Device tree describes, device tree defines Compatible binds, memory aligns Properties flow in key-value pairs Hierarchy shows what each component shares DTS compiles to DTB binary form Hardware topology takes its shape and form [Outro] Silicon speaks through structured syntax trees Hardware whispers carried on the breeze From DTS source to kernel's eager hands Device trees map these electronic lands
