880ffb5c6 Wanlong Gao 2011-05-05 95 * device driver's pm-ops.
7b08fae8f Marcos Paulo de Souza 2011-11-01 96 * @iommu_ops: IOMMU specific operations for this bus, used to attach IOMMU
ff21776d1 Joerg Roedel 2011-08-26 97 * driver implementations to a bus and allow the driver to do
ff21776d1 Joerg Roedel 2011-08-26 98 * bus-specific setup
880ffb5c6 Wanlong Gao 2011-05-05 99 * @p: The private data of the driver core, only the driver core can

880ffb5c6 Wanlong Gao 2011-05-05 105 * A bus is a channel between the processor and one or more devices. For the

880ffb5c6 Wanlong Gao 2011-05-05 107 * it is an internal, virtual, "platform" bus. Buses can plug into each other.
880ffb5c6 Wanlong Gao 2011-05-05 108 * A USB controller is usually a PCI device, for example. The device model
880ffb5c6 Wanlong Gao 2011-05-05 109 * represents the actual connections between buses and the devices they control.
880ffb5c6 Wanlong Gao 2011-05-05 110 * A bus is represented by the bus_type structure. It contains the name, the
880ffb5c6 Wanlong Gao 2011-05-05 111 * default attributes, the bus' methods, PM operations, and the driver core's
