Yes, that is what I meant. I believe most other watchdogs let
you program the timeout, but I don't see anything wrong with
having that fixed in the FPGA in your case.
Still, the choice of putting the timeout into DT in terms of
cycles rather than miliseconds wasn't ideal from an interface
perspective and we should change that if/when we do a generic
binding. I can definitely see where it's coming from for your
case, as the cycle count totally makes sense from an FPGA
tool perspective...
