frankly,the about are need be declared. but  there are 4 types[0] for 
trip in thermal framework,
there is no force-shut for me. So I want to change it three additional 
properties in [PATCH V4 4/4],

[0]
{
     THERMAL_TRIP_CRITICAL,
     THERMAL_TRIP_HOT,
     THERMAL_TRIP_PASSIVE,
     THERMAL_TRIP_ACTIVE,
}

It's a good option.
I can send a patch,but I don't know whether the thermal maintainers will 
accept it.

Maybe,they have a better way to suggest it.:-)

PS:I will sent a new patch If I still have no received their suggestions 
in two days.
