    dt: Add a check for undocumented compatible strings in kernel · b6acf807
    Rob Herring authored
    Add a make target, dt_compatible_check, to extract compatible strings
    from kernel sources and check if they are documented by a schema.
    At least version v2022.08 of dtschema with dt-check-compatible is
    required.
    
    This check can also be run manually on specific files or directories:
    
    scripts/dtc/dt-extract-compatibles drivers/clk/ | \
      xargs dt-check-compatible -v -s Documentation/devicetree/bindings/processed-schema.json
    
    Currently, there are about 3800 undocumented compatible strings. Most of
    these are cases where the binding is not yet converted (given there
    are 1900 .txt binding files remaining).
