203 Attribute is only present for zones in which the passive cooling
204 policy is not supported by native thermal driver. Default is zero
205 and can be set to a temperature (in millidegrees) to enable a
206 passive trip point for the zone. Activation is done by polling with
207 an interval of 1 second.
