The devicetree acts like a map of the hardware; it describes where each component is in register space, and stores configuration values for them. It also describes components located on buses like I2C and SPI, and can carry some metadata about the board/device (like the RAM size/base address, model code or chassis type). | The devicetree acts like a map of the hardware; it describes where each component is in register space, and stores configuration values for them.
