struct devfreq* devfreq_add_device	(	struct device *	dev,

	)

read

devfreq_add_device() - Add devfreq feature to the device : the device to add devfreq feature. : device-specific profile to run devfreq. : the policy to choose frequency. : private data for the governor. The devfreq framework does not touch this value.

Definition at line 347 of file devfreq.c.

struct opp* devfreq_recommended_opp	(	struct device *	dev,
		unsigned long *	freq,
		u32	flags
	)

read

devfreq_recommended_opp() - Helper function to get proper OPP for the freq value given to target callback. The devfreq user device. (parent of devfreq) The frequency given to target function Flags handed from devfreq framework.

Definition at line 649 of file devfreq.c.

int devfreq_register_opp_notifier	(	struct device *	dev,
		struct devfreq *	devfreq
	)

devfreq_register_opp_notifier() - Helper function to get devfreq notified for any changes in the OPP availability changes The devfreq user device. (parent of devfreq) The devfreq object.

Definition at line 680 of file devfreq.c.

int devfreq_remove_device ( struct devfreq * devfreq )

devfreq_remove_device() - Remove devfreq feature from a device. the devfreq instance to be removed

Definition at line 436 of file devfreq.c.

int devfreq_unregister_opp_notifier	(	struct device *	dev,
		struct devfreq *	devfreq
	)

devfreq_unregister_opp_notifier() - Helper function to stop getting devfreq notified for any changes in the OPP availability changes anymore. The devfreq user device. (parent of devfreq) The devfreq object.

At exit() callback of devfreq_dev_profile, this must be included if devfreq_recommended_opp is used.
