This is c3, not t7. Why do you use t7 compatible alone?

The C3 and T7 use the same watchdog controller, so they are compatible.

I am not saying that they are not compatible. I am saying that different
SoCs should use the same compatible. Just like for every other platform,
Amlogic is not special here.

Eh, missing "not", so "should not use":

I am not saying that they are not compatible. I am saying that different
SoCs should not use the same compatible. Just like for every other

Please define compatibility list with t7 as fallback.
