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.

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.
