[Verse 1] In the world of embedded design Device trees help us define Every chip and every pin Let the hardware mapping begin Nodes are containers holding data Properties describe each strata Curly braces wrap it tight Making hardware come to light [Chorus] Nodes and props and labels too References connecting through Forward slash means root is here Memory maps crystal clear DTS syntax guides the way Hardware speaks in structured play Learn the language, learn it well Device trees have tales to tell [Verse 2] Labels mark the spots you need At-symbols help your cross-refs feed Ampersand points to the name Linking nodes in hardware game Strings in quotes and numbers plain Cell arrays in memory lane Compatible strings declare What driver should handle there [Chorus] Nodes and props and labels too References connecting through Forward slash means root is here Memory maps crystal clear DTS syntax guides the way Hardware speaks in structured play Learn the language, learn it well Device trees have tales to tell [Bridge] GPIO pins and interrupt lines Clock sources keeping time Address cells and size cells count Memory ranges paramount Status okay or disabled state Reg properties don't hesitate Every board needs its own tree Hardware abstraction key [Verse 3] Inheritance flows down the chain Child nodes can override again Includes bring in common code Sharing down the hardware road Comments start with double slash Preprocessing in a flash Compile to binary form Bootloader performs transform [Chorus] Nodes and props and labels too References connecting through Forward slash means root is here Memory maps crystal clear DTS syntax guides the way Hardware speaks in structured play Learn the language, learn it well Device trees have tales to tell [Outro] From source to blob the journey's made Device tree foundation laid Read and write with confidence Hardware abstraction makes sense
