91 struct device represents a single device. It mainly contains metadata
92 describing the relationship the device has to other entities. 
95 - Embed a struct device in the bus-specific device type. 
100        struct  device  dev;            /* Generic device interface */
104   It is recommended that the generic device not be the first item in

142   Also, the location of the device's sysfs directory depends on a
143   device's parent. sysfs exports a directory structure that mirrors 
144   the device hierarchy. Accurately setting the parent guarantees that
147   The device's bus field is a pointer to the bus type the device
151   Optionally, the bus driver may set the device's name and release
154   The name field is an ASCII string describing the device, like

163 - Register the device. 
165   Once the generic device has been initialized, it can be registered
175   If a bus driver unregisters a device, it should not immediately free
177   device's release method, then free the bus-specific object.

328 The model assumes that a device or driver can be dynamically
333 A driver typically contains a list of device IDs that it supports. The
335 The format of the device IDs, and the semantics for comparing them are
341   int (*match)(struct device * dev, struct device_driver * drv);
343 match should return '1' if the driver supports the device, and '0'
346 When a device is registered, the bus's list of drivers is iterated
350 over. bus->match() is called for each device that is not already
353 When a device is successfully bound to a driver, device->driver is
354 set, the device is added to a per-driver list of devices, and a
356 device's physical directory:
