      ftgmac100: Remove redundant judgement · 86eeb97d
      tangbin authored
      In this function, ftgmac100_probe() can be triggered only
      if the platform_device and platform_driver matches, so the
      judgement at the beginning is redundant.

      ath9k: Handle txpower changes even when TPC is disabled · 968ae2ca
      Remi Pommarel authored
      When TPC is disabled IEEE80211_CONF_CHANGE_POWER event can be handled to
      reconfigure HW's maximum txpower.
      
      This fixes 0dBm txpower setting when user attaches to an interface for
      the first time with the following scenario:
      
      ieee80211_do_open()
          ath9k_add_interface()
              ath9k_set_txpower() /* Set TX power with not yet initialized
                                     sc->hw->conf.power_level */
      
          ieee80211_hw_config() /* Iniatilize sc->hw->conf.power_level and
                                   raise IEEE80211_CONF_CHANGE_POWER */
      
          ath9k_config() /* IEEE80211_CONF_CHANGE_POWER is ignored */
      
      This issue can be reproduced with the following:
      
        $ modprobe -r ath9k
        $ modprobe ath9k
        $ wpa_supplicant -i wlan0 -c /tmp/wpa.conf &
        $ iw dev /* Here TX power is either 0 or 3 depending on RF chain */
        $ killall wpa_supplicant
        $ iw dev /* TX power goes back to calibrated value and subsequent
                    calls will be fine */

      ath5k: Add proper dependency for ATH5K_AHB · c98cdaef
      Krzysztof Kozlowski authored
      The CONFIG_ATH5K_AHB could be enabled on ATH25 system without enabling
      ATH5K driver itself.  This does not make sense because CONFIG_ATH5K_AHB
      controls object build within drivers/net/wireless/ath/ath5k/ so enabling
      it without CONFIG_ATH5K brings nothing.
      
      Add proper dependency to CONFIG_ATH5K_AHB.

      ath11k: add thermal sensor device support · a41d1034
      Pradeep Kumar Chitrapu authored
      Temperature sensor generates electrical analog voltage from temperature
      of each chain. The analog voltage is converted to digital value through
      ADC. For reading temperature values fom user space, hw monitoring device
      is used.
      
      Whenever the user requests for current temperature, the driver sends WMI
      command and wait for response. For reading temperature,
      
      cat /sys/class/ieee80211/phy*/device/hwmon/hwmon2/temp1_input

      ath11k: add thermal cooling device support · 2a63bbca
      Pradeep Kumar Chitrapu authored
      Thermal cooling device support is added to control the temperature by
      throttling the data transmission for the given duration. Throttling is
      done by suspending all data tx queues by given percentage of time. The
      thermal device allows user to configure duty cycle.
      
      Throttling can be disabled by setting the duty cycle to 0. The cooling
      device can be found under /sys/class/thermal/cooling_deviceX/.
      Corresponding soft link to this device can be found under phy folder.
      
      /sys/class/ieee80211/phy*/device/cooling_device.
      
      To set duty cycle as 40%,
      
      echo 40 >/sys/class/ieee80211/phy*/device/cooling_device/cur_state
