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.
