[Verse 1]
When bootloaders wake the silicon dawn
ARM processors stretch but hardware's withdrawn
No buses to scan like x86 knows
So device trees bloom where the kernel goes
Flattened binary speaks in structured tongue
Properties nested where components hung
[Chorus]
Device tree source becomes the map
Compiled to blob the kernel unwraps
Nodes and properties, hierarchy clear
Compatible strings make drivers appear
DTS to DTB, the hardware tale
Memory addresses never fail
[Verse 2]
Root node branches to the system spine
CPU cores and memory regions align
Each device node holds its vital stats
Interrupt numbers and register mats
Phandles point where connections thread
Parent-child relationships widespread
[Chorus]
Device tree source becomes the map
Compiled to blob the kernel unwraps
Nodes and properties, hierarchy clear
Compatible strings make drivers appear
DTS to DTB, the hardware tale
Memory addresses never fail
[Bridge]
Device tree compiler transforms the code
From human syntax to binary load
U-Boot passes the flattened tree
Kernel parser sets hardware free
Matching drivers to compatible names
Platform devices in kernel domains
[Verse 3]
GPIO banks and I2C lanes described
SPI controllers where peripherals hide
Clock frequencies and voltage rails
Pin multiplexing never fails
Status okay or disabled state
Device enumeration sealed by fate
[Chorus]
Device tree source becomes the map
Compiled to blob the kernel unwraps
Nodes and properties, hierarchy clear
Compatible strings make drivers appear
DTS to DTB, the hardware tale
Memory addresses never fail
[Outro]
From bootloader handoff to driver bind
Device trees connect hardware minds
Topology mapped in structured form
Embedded systems perform
