DTSh

DTSh is a Devicetree Source (DTS) files viewer with a shell-like command line interface:

• navigate and visualize the devicetree

• search for devices, bindings, buses or interrupts with flexible criteria

• redirect command output to files (text, HTML, SVG) to document hardware configurations or illustrate notes

• rich Textual User Interface, command line auto-completion, command history, user themes

You can use it with:

• all DTS files generated by Zephyr at build-time (aka build/zephyr/zephyr.dts)

• arbitrary DTS files with bindings compatible with Zephyr’s Devicetre bindings syntax
