I don't think any other in-kernel watchdog driver has to deal with write-once hardware. On these processors once the watchdog register is programmed, it cannot be disabled or re-programmed. If the above behaviour is required, then we might aswell remove the ioctl(WDIOC_SETTIMEOUT) interface for this driver since if the user wants anything other than the default timeout they would need to pass it via the kernel command-line or module parameters.
