This patch adds notification support for those clients of cpu_cooling
APIs which may want to do something extra after receiving these
cpu_cooling events shown below. The notifier structure passed is of both Set/Get type.
The notfications events can be of the following type,
The advantages of these notfications is to differentiate between different
P states in the cpufreq table and the cooling states. The clients of these
events may group few P states into 1 cooling states as done by ACPI .
Also some more cooling states can be enabled when the maximum of P state is
reached. In case of ACPI processor throttling are enabled when minimum
P-state is reached. Post notification events can be used for those cases.
Amit Daniel Kachhap (5):
thermal: cpu_cooling: Support passing driver private data.
thermal: cpu_cooling: Add notifications support for the clients
thermal: cpu_cooling: Add support to find nearby frequency levels.
thermal: cpu_cooling: Release the upper cooling limit checks
ACPI: thermal: processor: Use the generic cpufreq infrastructure
