To that end I need a formal definition of the DTS grammar. While I have found the dtc tool, all its source files (in particular the dtc-lexer.l and dtc-parser.y files) are released under GPL, so it isn't entirely clear whether I may use the grammar encoded in those and transcribe that into my own (I'm writing my tool in Java, most likely using the JavaCC parser generator tool). So, is there another place where the grammar of Device Tree source files is formally defined in ways that allows tools developers to use that ? Any help and advice would be highly appreciated.
