[PATCH v3 00/11] dtc: dt-check-style: Improvements for false positives
From: Krzysztof Kozlowski
Date: Mon Aug 03 2026 - 05:04:09 EST
Changes in v3:
- Responded to Sashiko and implemented its comments
- Properly handle root node with more than one space "/ {"
- Add more unit tests for DTSO whether properties and nodes are properly
detected as top-level
- Link to v2: https://patch.msgid.link/20260802-n-dts-style-checker-continued-v2-0-6c5dbd1ccfe4@xxxxxxxxxxxxxxxx
Changes in v2:
- Trailing slash to maintainers path
- New patches:
- Patch #9: dtc: dt-check-style: Add test for trailing white-space in DTS
- Patch #10: dtc: dt-check-style: Add warning for redundant white-spaces
- Several fixes based on Sashiko's report (I responded to these on the
lists)
- _walk_bodies(): Fix setting up proper parent to each node after
exiting node parsing. This wasn't working correctly.
- check_child_name_order(): Properly sort top-level nodes by names,
even if it comes with unit address like memory@1000
- Add rest of property_bucket sorting for top-level properties,
even though no properties are expected there, except few vendor
ones
- check_continuation_alignment(): Improve error msg for
continuned-lines alignment warnings
- Link to v1: https://patch.msgid.link/20260726-n-dts-style-checker-continued-v1-0-b05b8f897670@xxxxxxxxxxxxxxxx
Few improvements and proper handling of top-level node (name, not unit
address sorting) and property (model before compatible) sorting.
Best regards,
Krzysztof
