| /** |
| * 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 |
