+/**
+ * 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
