Structured Documentation and Validation for Device Tree
summary
A prototype validates Devicetree bindings and generates documentation using a Python 3 prototype that encodes DTS as YAML + JSON Schema and renders docs with Sphinx; the core validator is lightweight (~250 lines of code, metaschema ~202 lines) and already flags real errors in a Juno DTB while producing usable error locations. It presently validates assembled DTBs, supports a metaschema for schema files, and works but needs broader coverage, dtc integration, and conversion of kernel bindings to the structured format.
