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.
