Subject: [PATCH v2] dt-bindings: watchdog: davinci-wdt: convert txt to yaml
Convert txt file to yaml.
Add maintainers list, based on the git history.
Mark clock as required property, by reviewer's suggestion.
Signed-off-by: Nik Bune <n2h9z4@...il.com>

Changes in v2 (according to review comments):
- Added clocks to the list of required properties.
- Updated clocks property to have only maxItems without $ref and description.
- Removed timeout-sec explicit definition, as it is defined in watchdog.yaml.
- Updated maintainers list from the git history.
