+CPU cooling APIs How To
+===================================

+
+0. Introduction
+
+The generic cpu cooling(freq clipping, cpuhotplug etc) 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. cpu cooling APIs
+
+1.1 cpufreq registration/unregistration APIs
+1.1.1 struct thermal_cooling_device *cpufreq_cooling_register(
+	struct freq_clip_table *tab_ptr, unsigned int tab_size)
+
+    This interface function registers the cpufreq cooling device with the name
+    "thermal-cpufreq-%x". This api can support multiple instances of cpufreq
+    cooling devices.
+
+    tab_ptr: The table containing the maximum value of frequency to be clipped
+    for each cooling state.
+	.freq_clip_max: Value of frequency to be clipped for each allowed
+	 cpus.
+	.temp_level: Temperature level at which the frequency clamping will
+	happen.
+	.mask_val: cpumask of the allowed cpu's
+    tab_size: the total number of cpufreq cooling states.
+
+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.
+
+
+1.2 CPU cooling action notifier register/unregister interface
+1.2.1 int cputherm_register_notifier(struct notifier_block *nb,
+	unsigned int list)
+
+    This interface registers a driver with cpu cooling layer. The driver will
+    be notified when any cpu cooling action is called.
+
+    nb: notifier function to register
+    list: CPUFREQ_COOLING_START or CPUFREQ_COOLING_STOP
+
+1.2.2 int cputherm_unregister_notifier(struct notifier_block *nb,
+	unsigned int list)
+
+    This interface registers a driver with cpu cooling layer. The driver will
+    be notified when any cpu cooling action is called.
+
+    nb: notifier function to register
+    list: CPUFREQ_COOLING_START or CPUFREQ_COOLING_STOP
