* 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

* DOC: encapsulation and type safety
*
* 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.
