You cannot add new required properties as that is an ABI break. If there's only 1 SCU instance, you can just fetch its node by compatible with no DT change. What's the plan for converting this binding to schema? This is the 2nd new property in 6 months. Rob

I had a patch converting it in a local branch which I've now sent: https://lore.kernel.org/all/20240402120118.282035-1-andrew@codeconstruct.com.au/ Perhaps we can pull it into this series? Andrew
Thanks, I can wait you update it and send a new version for wdt driver.

I've sent v2:
https://lore.kernel.org/linux-watchdog/20240403020439.418788-1-andrew@codeconstruct.com.au/
Rob's okay with it:
https://lore.kernel.org/linux-watchdog/20240403171321.GA3996007-robh@kernel.org/
Feel free to address his comment there if you integrate it into your
series, though make sure to add his tag, keep my authorship, and append
your own S-o-b if you do.
