89 * DOC: Driver system flows - drv component
90 *
91 * This component implements the system flows such as bus enumeration, bus
92 * removal. Bus dependent parts of system flows (such as iwl_pci_probe) are in
93 * bus specific files (transport files). This is the code that is common among
94 * different buses.
95 *
96 * This component is also in charge of managing the several implementations of
97 * the wifi flows: it will allow to have several fw API implementation. These
98 * different implementations will differ in the way they implement mac80211's
99 * handlers too.
100
101 * The init flow wrt to the drv component looks like this:
102 * 1) The bus specific component is called from module_init
103 * 2) The bus specific component registers the bus driver
104 * 3) The bus driver calls the probe function
105 * 4) The bus specific component configures the bus
106 * 5) The bus specific component calls to the drv bus agnostic part
107 * (iwl_drv_start)
1c8e11e1
EG
108 * 6) iwl_drv_start fetches the fw ASYNC, iwl_req_fw_callback
109 * 7) iwl_req_fw_callback parses the fw file
110 * 8) iwl_req_fw_callback starts the wifi implementation to matches the fw
