Lines Matching full:device
25 * struct bus_type - The bus type of the device
31 * @drv_groups: Default attributes of the device drivers on the bus.
32 * @match: Called, perhaps multiple times, whenever a new device or driver
34 * given device can be handled by the given driver and zero
36 * the driver supports the device is not possible. In case of
37 * -EPROBE_DEFER it will queue the device for deferred probing.
38 * @uevent: Called when a device is added, removed, or a few other things
40 * @probe: Called when a new device or driver add to this bus, and callback
41 * the specific driver's probe to initial the matched device.
42 * @sync_state: Called to sync device state to software state after all the
43 * state tracking consumers linked to this device (present at
45 * driver. If the device has no consumers, this function will
46 * be called at late_initcall_sync level. If the device has
49 * @remove: Called when a device removed from this bus.
50 * @shutdown: Called at shut-down time to quiesce the device.
51 * @irq_get_affinity: Get IRQ affinity mask for the device on this bus.
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
62 * @dma_cleanup: Called to cleanup DMA configuration on a device on
65 * device driver's pm-ops.
66 * @need_parent_lock: When probing or removing a device on this bus, the
67 * device core should lock the device's parent.
70 * purposes of the device model, all devices are connected via a bus, even if
72 * A USB controller is usually a PCI device, for example. The device model
