Lines Matching full:device
25 * struct bus_type - The bus type of the device
29 * @dev_root: Default device to use as the parent.
32 * @drv_groups: Default attributes of the device drivers on the bus.
33 * @match: Called, perhaps multiple times, whenever a new device or driver
35 * given device can be handled by the given driver and zero
37 * the driver supports the device is not possible. In case of
38 * -EPROBE_DEFER it will queue the device for deferred probing.
39 * @uevent: Called when a device is added, removed, or a few other things
41 * @probe: Called when a new device or driver add to this bus, and callback
42 * the specific driver's probe to initial the matched device.
43 * @sync_state: Called to sync device state to software state after all the
44 * state tracking consumers linked to this device (present at
46 * driver. If the device has no consumers, this function will
47 * be called at late_initcall_sync level. If the device has
50 * @remove: Called when a device removed from this bus.
51 * @shutdown: Called at shut-down time to quiesce the device.
53 * @online: Called to put the device back online (after offlining it).
54 * @offline: Called to put the device offline for hot-removal. May fail.
56 * @suspend: Called when a device on this bus wants to go to sleep mode.
57 * @resume: Called to bring a device on this bus out of sleep mode.
58 * @num_vf: Called to find out how many virtual functions a device on this
60 * @dma_configure: Called to setup DMA configuration on a device on
63 * device driver's pm-ops.
70 * @need_parent_lock: When probing or removing a device on this bus, the
71 * device core should lock the device's parent.
74 * purposes of the device model, all devices are connected via a bus, even if
76 * A USB controller is usually a PCI device, for example. The device model
