| The generic cpu cooling(freq clipping) provides registration/unregistration APIs |
| to the caller. The binding of the cooling devices to the trip point is left for |
| the user. The registration APIs returns the cooling device pointer. |
| 1.1 cpufreq registration/unregistration APIs |
| 1.1.1 struct thermal_cooling_device *cpufreq_cooling_register( |
| struct cpumask *clip_cpus) |
| This interface function registers the cpufreq cooling device with the name |
| "thermal-cpufreq-%x". This api can support multiple instances of cpufreq |
| clip_cpus: cpumask of cpus where the frequency constraints will happen. |
| 1.1.2 void cpufreq_cooling_unregister(struct thermal_cooling_device *cdev) |
| This interface function unregisters the "thermal-cpufreq-%x" cooling device. |
| cdev: Cooling device pointer which has to be unregistered. |
