Devicetree tools

🚧 NOTE: dt-tools is very experimental and is currently ongoing a rewrite!

dt-tools helps you to write, debug and read Devicetree files more efficiently with advanced tooling!

• IDE integration
• Linting
• Devicetree binding validation
• Preprocessor features, with some restrictions:
  • Macros can only substitute references (&-syntax), name definitions (of nodes, properties and labels), property values, cell values and items (like nodes and properties)
  • Macros must be parseable on their own. This is not allowed:

    #define SPECIAL_SYNTAX ) + (
    
    / {
      prop = (1 SPECIAL_SYNTAX 2);
    };
    
  • #include directives can only be used outside of nodes (note that this may change)
  • Conditionals can only wrap nodoes, properties and other preprocessor directives
    • 🚧 Currently fully unimplemented
    • Can only check for definition, equality or ordering
• Extensive unit and integration tests written in Rust
• Possibly in the future:
  • Comparing DTS or DTB files
  • Comparing Android dt and dtbo partitions with /sys/firmware/fdt

Crates

• dt-parser implements an error-resistant parser inspired by rust-analyzer
• dt-analyzer is a source file analyzer
• dt-lsp is a language server for devicetree
• dt-lint is a linter for DTS
• dt-binding-matcher is a crate supposed to validate and match devicetree binding YAMLs

Help needed

Any kinds of contributions are welcome! Just spreading awareness helps!

See the GitHub issues, especially the ones tagged with help wanted or good first issue.

If you can, take care of code containing TODO, FIXME, todo!(, unimplemented!( or similar

Contributing

Please read CONTRIBUTING.md.

LSP

The VSCode extension's documentation can be found here.

The language server is also packaged for Neovim with the ./crates/dt-lsp/lsp.lua script.

cd ./crates/dt-lsp
nvim -S lsp.lua ../../lint_showcase.dts

Features:

• Fast and safe parser and linter
• (TODO) View binding documentation straight from DTS!
• (TODO) Binding errors integrated into linter
