* iwl-bus.h defines the API to the bus layer of the iwlwifi driver.
|

* The bus layer is responsible for doing very basic bus operations that are
|
||||
* listed in the iwl_bus_ops structure.
|
||||
* The bus layer registers to the bus driver, advertises the supported HW and
|
||||
* gets notifications about enumeration, suspend, resume.
|
||||
* For the moment, the bus layer is not a linux kernel module as itself, and
|
||||
* the module_init function of the driver must call the bus specific
|
||||
* registration functions. These functions are listed at the end of this file.
|
||||
* For the moment, there is only one implementation of this interface: PCI-e.
|
||||
* This implementation is iwl-pci.c

* The iwl_bus describes the data that is shared amongst all the bus layer
|
||||
* implementations. This data is visible to other layers. Data in the bus
|
||||
* specific area is not visible outside the bus specific implementation.
|
||||
* iwl_bus holds a pointer to iwl_shared which holds pointer to all the other
|
||||
* layers of the driver (iwl_priv, iwl_trans). In fact, this is the way to go
|
||||
* when the transport layer needs to call a function of another layer.
|
||||
*
|
||||
* In order to achieve encapsulation, iwl_priv cannot be dereferenced from the
|
||||
* bus layer. Type safety is still kept since functions that gets iwl_priv gets
|
||||
* a typed pointer (as opposed to void *).

|

* will call the bus specific probe function.
|
||||
* The first thing this function must do is to allocate the memory needed by
|
||||
* iwl_bus + the bus_specific data.
|
||||
* Once the bus specific probe function has configured the hardware, it
|
||||
* chooses the appropriate transport layer and calls iwl_probe that will run
|
||||
* the bus independent probe flow.
|
||||
*
|

* Note: The bus specific code must set the following data in iwl_bus before it
|
