/**
|
||
|
|
* DOC: Driver system flows - drv component
|
||
|
|
*
|
||
|
|
* This component implements the system flows such as bus enumeration, bus
|
||
|
|
* removal. Bus dependent parts of system flows (such as iwl_pci_probe) are in
|
||
|
|
* bus specific files (transport files). This is the code that is common among
|
||
|
|
* different buses.
|
||
|
|
*
|
||
|
|
* This component is also in charge of managing the several implementations of
|
||
|
|
* the wifi flows: it will allow to have several fw API implementation. These
|
||
|
|
* different implementations will differ in the way they implement mac80211's
|
||
|
|
* handlers too.
|
||
|
|
|
||
|
|
* The init flow wrt to the drv component looks like this:
|
||
|
|
* 1) The bus specific component is called from module_init
|
||
|
|
* 2) The bus specific component registers the bus driver
|
||
|
|
* 3) The bus driver calls the probe function
|
||
|
|
* 4) The bus specific component configures the bus
|
||
|
|
* 5) The bus specific component calls to the drv bus agnostic part
|
||
|
|
* (iwl_drv_start)
|
||
|
|
* 6) iwl_drv_start fetches the fw ASYNC, iwl_req_fw_callback
|
||
|
|
* 7) iwl_req_fw_callback parses the fw file
|
||
|
|
* 8) iwl_req_fw_callback starts the wifi implementation to matches the fw
