'timeout'. Not used if max_hw_heartbeat_ms is non-zero.
* min_hw_heartbeat_ms: Minimum time between heartbeats sent to the chip,
in milli-seconds.
* min_hw_heartbeat_ms: Hardware limit for minimum time between heartbeats,
in milli-seconds. This value is normally 0; it should only be provided
if the hardware can not tolerate lower intervals between heartbeats.
* max_hw_heartbeat_ms: Maximum hardware heartbeat, in milli-seconds.
If set, the infrastructure will send heartbeats to the watchdog driver
if 'timeout' is larger than max_hw_heartbeat_ms, unless WDOG_ACTIVE
