This directory contains devicetree source (.dts) and binary (.dtb) files for use in devicetree tests. Every ‘dtb’ file is obtained from a device, and the respective ‘.dts’ file is decompiled from the binary format.
It is important that ‘dtb’s in this directory reflect the contents of real or virtual hardware. This blobs may be constructed by bootloaders, may be broken in different ways and recompiling them from the decompiled ‘dts’ is not guaranteed to provide bit-for-bit equality.
When adding a new binary file, it shall be named after the board and include any meaningul information, such as ‘qemu-gic3’. Added files should be decompiled using the devicetree compiler application, and submitted together with the corresponding binary file.
The ‘synthetic’ directory contains devicetree source (.dts) for use in devicetree tests. Unlike the data contained in this directory, the synthetic ‘dtb’ are compiled from handwritten ‘dts’ files.
