* iwlwifi: wrt: add fw force restart via triggersShahar S Matityahu2018-03-28
| | | | | | | | | | | | We can set triggers that cause a debug data collection when something of interest happens (e.g. when too many probes are lost conscutively). Normally, this triggers don't cause the FW to be restarted, but in some cases that may be desired, so we recover from the problem. To support this, add a flag that indicates that the FW should be restarted when the trigger fires.

| * iwlwifi: add shared clock PHY config flag for some devicesLuca Coelho2018-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | Some devices use a shared clock which is very sensitive to variations and cause trouble in some situations. We need to set a bit in the phy configuration to indicate that to the FW. To make this generic, add a extra_phy_config_flags element to the device configuration and OR it into the phy_cfg before sending it to the firmware. And also create a set of configurations for devices that use shared clocks and need this extra bit to be set.

* iwlwifi: avoid collecting firmware dump if not loadedShaul Triebitz2018-03-02
| | | | | | | | | | | | | | | Trying to collect firmware debug data while firmware is not loaded causes various errors (e.g. failing NIC access). This causes even a bigger issue if at that time the HW radio is off. In that case, when later turning the radio on, the Driver fails to read the HW (registers contain garbage values). (It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN bit is cleared on faulty NIC access - since the same behavior was seen in HW RFKILL toggling before setting that bit.)

* iwlwifi: mvm: Fix channel switch for count 0 and 1Andrei Otcheretianski2018-03-02
| | | | | | | | | | | | | It was assumed that apply_time==0 implies immediate scheduling, which is wrong. Instead, the fw expects the START_IMMEDIATELY flag to be set. Otherwise, this resulted in 0x3063 assert. Fix that. While at it rename the T2_V2_START_IMMEDIATELY to TE_V2_START_IMMEDIATELY.

* iwlwifi: Cancel and set MARKER_CMD timer during suspend-resumeHaim Dreyfuss2018-03-02
| | | | | | | | | | | | | | While entering to D3 mode there is a gap between the time the driver handles the D3_CONFIG_CMD response to the time the host is going to sleep. In between there might be cases which MARKER_CMD can tailgate. Also during resume flow the MARKER_CMD might get sent while D0I3_CMD is being handled in the FW. Cancel MARKER_CMD timer and set it again properly during suspend resume flows to prevent this command from being sent accidentlly.

* iwlwifi: align timestamp cancel with timestamp startShaul Triebitz2018-02-16
| | | | | | | | | | | | Canceling the periodic timestamp work should be done in the opposite flow to where it was started. This also prevents from sending the MARKER command during the mac_stop flow - causing a false queue hang (FW is no longer there to send a response).

With this feature, the driver's responsiblity is to provide an initial configuration and to handle notifications regarding recent rates and some other parameters. Debugfs hooks will be still available for reading the current rate/statistics and setting a fixed rate. The old API is supported so far, though both APIs cannot be used simultaneously. This is the first patch in the series. It adds a new TLV specifying FW support for the new API and updates lq_sta to support two types of rate scaling.

One path is the IRQ calling stop device, and updating op mode and stack. As a result, cfg80211 is running rfkill sync work that shuts down all devices (second path). In the second path, we eventually get to iwl_mvm_stop_device which calls iwl_fw_dump_conf_clear->iwl_fw_dbg_stop_recording, that access periphery registers. The device may be stopped at this point from the first path, which will result with a failure to access those registers. Simply checking for the trans status is insufficient, since the race will still exist, only minimized. Instead, move the stop from iwl_fw_dump_conf_clear (which is getting called only from stop path) to the transport stop device function, where the access is always safe. This has the added value, of actually stopping dbgc before stopping device even when the stop is initiated from the transport.
