14 Each bus type in the kernel (PCI, USB, etc) should declare one static
31 When a bus driver is initialized, it calls bus_register. This
32 initializes the rest of the fields in the bus object and inserts it
33 into a global list of bus types. Once the bus object is registered, 
34 the fields in it are usable by the bus driver. 
44 them are inherently bus-specific. Drivers typically declare an array
45 of device IDs of devices they support that reside in a bus-specific
48 The purpose of the match callback is to give the bus an opportunity to
51 particular device, without sacrificing bus-specific functionality or

89 Each bus gets a directory in the bus directory, along with two default

96 Drivers registered with the bus get a directory in the bus's drivers

108 the bus's devices directory to the device's directory in the physical
