dtc: dt-check-style: Simplify setting depth of DtsLine

2026-08-14T20:43:24+00:00

When creating new DtsLine object, pass expected indentation depth as constructor, instead of assigning it immediately after, so the code will be easier to read and explicit (depth is not supposed to change during DtsLine lifetime).

dtc: dt-check-style: Add missing /dts-v1/ to few test cases

2026-08-14T20:43:23+00:00

The selftest DTS should still look like a real DTS, so it needs '/dts-v1/' marking. Signed-off-by: Krzysztof Kozlowski Link: https://patch.msgid.link/20260803-n-dts-style-checker-continued-v3-1-6c9776928cea@oss.qualcomm.com Signed-off-by: Rob Herring (Arm)

dtc: dt-check-style: Add more DTS test cases

2026-07-20T20:50:57+00:00

Add a few more test cases for valid and incorrect DTS for dt-check-style. Signed-off-by: Krzysztof Kozlowski Link: https://patch.msgid.link/20260709-dts-style-checker-v5-7-fcc147cb697d@oss.qualcomm.com Signed-off-by: Rob Herring (Arm)

dtc: dt-check-style: Print proper line number of indentation detection place

2026-07-20T20:50:57+00:00

Script judges the indentation however always suggests it is the first line which is wrong, e.g.: sigmastar/mstar-infinity2m.dtsi:1: [indent-unit-dts] indent unit must be 1 tab in DTS, got '\t\t' Signed-off-by: Krzysztof Kozlowski Link: https://patch.msgid.link/20260709-dts-style-checker-v5-6-fcc147cb697d@oss.qualcomm.com Signed-off-by: Rob Herring (Arm)

dtc: dt-check-style: Handle properly DTC-style includes

2026-07-20T20:50:57+00:00

dt-check-style was not properly handling DTC directives (starting with '/', e.g. /dts-v1/ or /include/), thus a few DTS files had false positive like: apm/apm-merlin.dts:1: [indent-unit-dts] indent unit must be 1 tab in DTS, got '\t\t' Signed-off-by: Krzysztof Kozlowski Link: https://patch.msgid.link/20260709-dts-style-checker-v5-5-fcc147cb697d@oss.qualcomm.com Signed-off-by: Rob Herring (Arm)

dtc: dt-check-style: Expect first device_type

2026-07-20T20:50:56+00:00

A few nodes do have "device_type" property which is mostly, but not always, the first property in a device node, when applicable. Adjust the DTS coding style rules to actually expect the device_type first and improve the dt-check-style to handle this correctly.

dtc: dt-check-style: Rework handling YAML/DTS in rules

2026-07-20T20:50:56+00:00

Individual rules behave differently depending whether they handle bindings (YAML) or DTS, but the code was focusing on type of indentation (spaces vs tabs). That indentation is actually irrelevant in some rules, so differentiate based on file type. This will be more relevant in the future when more rules act differently on DTS, than on bindings.

dtc: dt-check-style: Allow space-aligning indentation in DTS

2026-07-20T20:50:56+00:00

DTS often have spaces after tabs in indentation for aligning continued lines of comments or list properties, thus allow such cases to avoid many false positives. What we can easily detect is a space followed by tab or too many spaces (more than alignment). OTOH, DTS example in YAML files does not have tabs at all and there is already rule for that, thus there is no point to check for mixed indentation there.

dtc: dt-check-style: Narrow disallowing of tab in DTS only to YAML

2026-07-20T20:50:56+00:00

DTS in the bindings (example in a YAML file) does not have tabs at all, but regular DTS do, therefore entire check check_tab_in_dts() has confusing name and should apply only to YAML files.

dt-bindings: add self-test fixtures for style checker

2026-06-10T18:37:06+00:00

Provide good/ and bad/ DTS and YAML fixtures plus a small runner that feeds them to dt-check-style and diffs the output against expected text files. Wired into a new top-level dt_style_selftest make target so the suite can be exercised independently of the full tree.
