linting tool for dt files

[aparcar]

Hi, at OpenWrt there are sometimes badly styled DT files which waste human time to comment and fix, it would be nice to have some automatic checks for that. Is there a tool like astyle or clang-format for device tree files?

I don't think any such thing exists for .dts files. Something like that should probably live within dtc, not this project, as it could re-use the parsing logic.

We need something too now for DT schema files. There's tools/yaml-format in this repo that mainly just does a round trip thru ruamel, but it doesn't quite format how I'd like it to. There's also yamllint, but I haven't looked at it.

With dtc I'm sure you refer to this tool right? It supports dts as an output, however not linting. At OpenWrt many dts files contain comments, so converting back and forth for linting isn't feasible.

However, should I close this issue and reopen it at dtc?

That's a mirror. The "official" repo is: https://git.kernel.org/pub/scm/utils/dtc/dtc.git

I didn't say dtc supported linting. It can output .dts files, but you loose a lot more than comments.

I don't mind leaving the issue open here to track it. There's no issue tracking for dtc. You might want to raise the issue on devicetree-compiler@vger.kernel.org list.

Thanks, I sent a mail asking the same question. I'll update this issue once something happens
