2 CPU cooling APIs How To
14 The generic cpu cooling(freq clipping) provides registration/unregistration APIs
15 to the caller. The binding of the cooling devices to the trip point is left for
16 the user. The registration APIs returns the cooling device pointer.

29     This interface function registers the cpufreq cooling device with the name
30     "thermal-cpufreq-%x". This api can support multiple instances of cpufreq
31     cooling devices.
41     This interface function registers the cpufreq cooling device with
42     the name "thermal-cpufreq-%x" linking it with a device tree node, in
44     instances of cpufreq cooling devices.
54     This interface function unregisters the "thermal-cpufreq-%x" cooling device.
