[PATCH v3 00/11] dtc: dt-check-style: Improvements for false positives

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@oss.qualcomm.com

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@oss.qualcomm.com

Few improvements and proper handling of top-level node (name, not unit
address sorting) and property (model before compatible) sorting.

Best regards,
Krzysztof
