Thanks, I will re-word as mediatek,mt8173-smc-wdt, and address other comments.
In the event this does become a standard arm watchdog interface, I assume
but do not know that it will be straightforward to change the name here.

I am not sure how to proceed with modifying Julius' authored patch in
kernel preferred way.
I can add myself as co-authored-by and modify patch 2, or add a patch
3 to make preferred changes.

I will use approach 2 for now unless otherwise advised.
