The "critical" type trip in thermal zone can be
set to SOC_THERM hardware, it can trigger shut down
or reset event from hardware.

Note:
- the "critical" type trip points will be set to SOC_THERM hardware as the
shut down temperature. Once the temperature of this thermal zone is higher
than it, the system will be shutdown or reset by hardware.
