Hi linux-pm,

The linux thermal framework doesn't have any support for tracing. This
makes it hard to run workloads and observe the thermal behaviour of
the system without actively polling files in sysfs or enabling debug
builds.

This patch set introduces trace events in the framework to allow
observing the behaviour of the different components in the
framework. The events added trace temperature changes, trip points and
cooling device state changes.

The patches are based on v3.15-rc8.

Cheers,
Punit
