Looks to me like Content-Type header is missing. Usually, I get a prompt from git-send-email with what encoding to use if it needs to use UTF8. Rob

Two conversions to DT schema of GPIO watchdog binding happened and came through different trees. Merge them into one: 1. Combine maintainers, 2. Use more descriptive property descriptions and constraints from gpio-wdt.yaml, 3. Switch to unevaluatedProperties:false, to allow generic watchdog properties.
