struct thermal_cooling_device* thermal_cooling_device_register ( char *  type, void *  devdata, const struct thermal_cooling_device_ops *  ops  )

read

thermal_cooling_device_register - register a new thermal cooling device : the thermal cooling device type. : device private data. : standard thermal cooling devices callbacks.

void thermal_cooling_device_unregister

(

struct thermal_cooling_device *

)

thermal_cooling_device_unregister - removes the registered thermal cooling device : the thermal cooling device to remove.

thermal_cooling_device_unregister() must be called when the device is no longer needed.

		int	trip,
		struct thermal_cooling_device *	cdev,
		unsigned long	upper,
		unsigned long	lower
	)

thermal_zone_bind_cooling_device - bind a cooling device to a thermal zone : thermal zone device : indicates which trip point the cooling devices is associated with in this thermal zone. : thermal cooling device

This function is usually called in the thermal zone device .bind callback.

Definition at line 733 of file thermal_sys.c.

struct thermal_zone_device* thermal_zone_device_register ( const char *  type, int  trips, int  mask, void *  devdata, const struct thermal_zone_device_ops *  ops, int  passive_delay, int  polling_delay  )

read

thermal_zone_device_register - register a new thermal zone device : the thermal zone device type : the number of trip points the thermal zone support : a bit string indicating the writeablility of trip points : private device data : standard thermal zone device callbacks : number of milliseconds to wait between polls when performing passive cooling : number of milliseconds to wait between polls when checking whether trip points have been crossed (0 for interrupt driven systems)

thermal_zone_device_unregister() must be called when the device is no longer needed. The passive cooling depends on the .get_trend() return value.

	)

thermal_zone_unbind_cooling_device - unbind a cooling device from a thermal zone : thermal zone device : indicates which trip point the cooling devices is associated with in this thermal zone. : thermal cooling device

This function is usually called in the thermal zone device .unbind callback.
