Function Documentation

int attribute_container_add_attrs

(

struct device *

classdev

)

attribute_container_add_attrs - add attributes

: The class device

This simply creates all the class device sysfs files from the attributes listed in the container

Definition at line 315 of file attribute_container.c.

int attribute_container_add_class_device

(

struct device *

classdev

)

attribute_container_add_class_device - same function as device_add

: the class device to add

This performs essentially the same function as device_add except for attribute containers, namely add the classdev to the system and then create the attribute files

Definition at line 350 of file attribute_container.c.

int attribute_container_add_class_device_adapter	(	struct attribute_container *	cont,
		struct device *	dev,
		struct device *	classdev
	)

attribute_container_add_class_device_adapter - simple adapter for triggers

This function is identical to attribute_container_add_class_device except that it is designed to be called from the triggers

Definition at line 365 of file attribute_container.c.

void attribute_container_add_device	(	struct device *	dev,
		int(*)(struct attribute_container *, struct device *, struct device *)	fn
	)

Definition at line 142 of file attribute_container.c.

void attribute_container_class_device_del

(

struct device *

classdev

)

attribute_container_class_device_del - equivalent of class_device_del

: the class device

This function simply removes all the attribute files and then calls device_del.

Definition at line 407 of file attribute_container.c.

struct device_attribute** attribute_container_classdev_to_attrs ( const struct device *  classdev )

read

struct attribute_container* attribute_container_classdev_to_container ( struct device *  classdev )

read

attribute_container_classdev_to_container - given a classdev, return the container

: the class device created by attribute_container_add_device.

Returns the container associated with this classdev.

Definition at line 56 of file attribute_container.c.

void attribute_container_create_device	(	struct device *	dev,
		int(*)(struct attribute_container *, struct device *, struct device *)	fn
	)

void attribute_container_device_trigger	(	struct device *	dev,
		int(*)(struct attribute_container *, struct device *, struct device *)	fn
	)

Definition at line 251 of file attribute_container.c.

struct device* attribute_container_find_class_device ( struct attribute_container *  cont, struct device *  dev  )

read

attribute_container_find_class_device - find the corresponding class_device

: the container : the generic device

Looks up the device in the container's list of class devices and returns the corresponding class_device.

Definition at line 423 of file attribute_container.c.

int attribute_container_register

(

struct attribute_container *

cont

)

attribute_container_register - register an attribute container

: The container to register. This must be allocated by the callee and should also be zeroed by it.

Definition at line 75 of file attribute_container.c.

void attribute_container_remove_attrs

(

struct device *

classdev

)

attribute_container_remove_attrs - remove any attribute files

: The class device to remove the files from

Definition at line 379 of file attribute_container.c.

void attribute_container_remove_device	(	struct device *	dev,
		void(*)(struct attribute_container *, struct device *, struct device *)	fn
	)

Definition at line 207 of file attribute_container.c.

void attribute_container_trigger	(	struct device *	dev,
		int(*)(struct attribute_container *, struct device *)	fn
	)

Definition at line 292 of file attribute_container.c.

int __must_check attribute_container_unregister

(

struct attribute_container *

cont

)

attribute_container_unregister - remove a container registration

: previously registered container to remove
