TRANSPORT_SETUP_DEVI(9) 				   Device drivers infrastructure				   TRANSPORT_SETUP_DEVI(9)

NAME
transport_setup_device - declare a new dev for transport class association but don't make it visible yet. SYNOPSIS
void transport_setup_device(struct device * dev); ARGUMENTS
dev the generic device representing the entity being added DESCRIPTION
Usually, dev represents some component in the HBA system (either the HBA itself or a device remote across the HBA bus). This routine is simply a trigger point to see if any set of transport classes wishes to associate with the added device. This allocates storage for the class device and initialises it, but does not yet add it to the system or add attributes to it (you do this with transport_add_device). If you have no need for a separate setup and add operations, use transport_register_device (see transport_class.h). COPYRIGHT

struct_bus_type - The bus type of the device SYNOPSIS
struct bus_type { const char * name; const char * dev_name; struct device * dev_root; struct bus_attribute * bus_attrs; struct device_attribute * dev_attrs; struct driver_attribute * drv_attrs; const struct attribute_group ** bus_groups; const struct attribute_group ** dev_groups; const struct attribute_group ** drv_groups; int (* match) (struct device *dev, struct device_driver *drv); int (* uevent) (struct device *dev, struct kobj_uevent_env *env); int (* probe) (struct device *dev); int (* remove) (struct device *dev); void (* shutdown) (struct device *dev); int (* online) (struct device *dev); int (* offline) (struct device *dev); int (* suspend) (struct device *dev, pm_message_t state); int (* resume) (struct device *dev); const struct dev_pm_ops * pm; struct iommu_ops * iommu_ops; struct subsys_private * p; }; MEMBERS
name The name of the bus. dev_name Used for subsystems to enumerate devices like ("foou", dev->id). dev_root Default device to use as the parent. bus_attrs Default attributes of the bus. dev_attrs Default attributes of the devices on the bus. drv_attrs Default attributes of the device drivers on the bus. bus_groups Default attributes of the bus. dev_groups Default attributes of the devices on the bus. drv_groups Default attributes of the device drivers on the bus. match Called, perhaps multiple times, whenever a new device or driver is added for this bus. It should return a nonzero value if the given device can be handled by the given driver. uevent Called when a device is added, removed, or a few other things that generate uevents to add the environment variables. probe Called when a new device or driver add to this bus, and callback the specific driver's probe to initial the matched device. remove Called when a device removed from this bus. shutdown Called at shut-down time to quiesce the device. online Called to put the device back online (after offlining it). offline Called to put the device offline for hot-removal. May fail. suspend Called when a device on this bus wants to go to sleep mode. resume Called to bring a device on this bus out of sleep mode. pm Power management operations of this bus, callback the specific device driver's pm-ops. iommu_ops IOMMU specific operations for this bus, used to attach IOMMU driver implementations to a bus and allow the driver to do bus-specific setup p The private data of the driver core, only the driver core can touch this. DESCRIPTION
A bus is a channel between the processor and one or more devices. For the purposes of the device model, all devices are connected via a bus, even if it is an internal, virtual, "platform" bus. Buses can plug into each other. A USB controller is usually a PCI device, for example. The device model represents the actual connections between buses and the devices they control. A bus is represented by the bus_type structure. It contains the name, the default attributes, the bus' methods, PM operations, and the driver core's private data. COPYRIGHT
