There is no such binding for R63455.

What check failure? Please paste actual warnings (but not fake ones).

I do not get why all bindings now get completely flexible number of
resets. I am pretty sure not all of them constrain that. It's rather
your task to check it and explain in commit msg.
For example the second random I took to check (ILI7807S) does not
restrict, so you just made that binding accepting 1000 reset lines. Why?
Best regards,
