58  * @post_bind: Called after a new device is bound to this uclass
59  * @pre_unbind: Called before a device is unbound from this uclass
60  * @pre_probe: Called before a new device is probed
61  * @post_probe: Called after a new device is probed
62  * @pre_remove: Called before a device is removed
63  * @child_post_bind: Called after a child is bound to a device in this uclass
71  * @per_device_auto_alloc_size: Each device can hold private data owned
74  * @per_device_platdata_auto_alloc_size: Each device can hold platform data
77  * @per_child_auto_alloc_size: Each child device (of a parent in this
78  * uclass) can hold parent data for the device/uclass. This value is only
82  * in the child device's parent_platdata pointer. This value is only used as

171  * uclass_get_device_by_seq() - Get a uclass device based on an ID and sequence
173  * If an active device has this sequence it will be returned. If there is no
174  * such device then this will check for a device that is requesting this
177  * The device is probed to activate it ready for use.
181  * @devp: Returns pointer to device (there is only one for each seq)
187  * uclass_get_device_by_of_offset() - Get a uclass device by device tree node
190  * device tree node.
192  * The device is probed to activate it ready for use.
195  * @node: Device tree offset to search for (if -ve then -ENODEV is returned)

206  * device tree node.
208  * The device is probed to activate it ready for use.
211  * @np: Device tree node to search for (if NULL then -ENODEV is returned)
212  * @devp: Returns pointer to device (there is only one for each node)
219  * uclass_get_device_by_phandle_id() - Get a uclass device by phandle id
223  * The device is probed to activate it ready for use.
227  * @devp: Returns pointer to device (there is only one for each node)
228  * @return 0 if OK, -ENODEV if there is no device match the phandle, other

252  * uclass_get_device_by_driver() - Get a uclass device for a driver
258  * The device is probed to activate it ready for use.
262  * @devp: Returns pointer to the first device with that driver
269  * uclass_first_device() - Get the first device in a uclass
271  * The device returned is probed if necessary, and ready for use
277  * @devp: Returns pointer to the first device in that uclass if no error
278  * occurred, or NULL if there is no first device, or an error occurred with
279  * that device.
285  * uclass_first_device_err() - Get the first device in a uclass
287  * The device returned is probed if necessary, and ready for use
290  * @devp: Returns pointer to the first device in that uclass, or NULL if none
296  * uclass_next_device() - Get the next device in a uclass
298  * The device returned is probed if necessary, and ready for use
303  * @devp: On entry, pointer to device to lookup. On exit, returns pointer
304  * to the next device in the uclass if no error occurred, or NULL if there is
305  * no next device, or an error occurred with that next device.
