This is a Sublime Text 3 highlighter for Devicetree files; dts and dtsi.
You can send pull requests via GitHub. Do not edit the devicetree.tmLanguage file directly. Edit the devicetree.YAML-tmLanguage file instead and build the .tmLanguage file from it using the Build With: Convert to ... - Property List build tool in PackageDev. You can also use the key F7 to open up the build menu.
