      wlcore: Use generic runtime pm calls for wowlan elp configuration · 45aa7f07
      Eyal Reizer authored
      With runtime PM enabled, we can now use calls to pm_runtime_force_suspend
      and pm_runtime_force_resume for enabling elp during suspend when wowlan
      is enabled and waking the chip from elp on resume.
      
      Remove the custom API that was used to ensure that the command
      that is used to allow ELP during suspend is completed before the system
      suspend.

      wlcore: Fix timout errors after recovery · db68052b
      Tony Lindgren authored
      After enabling runtime PM, if we force hardware reset multiple times with:
      
      # echo 1 > /sys/kernel/debug/ieee80211/phy0/wlcore/start_recovery
      
      We will after few tries get the following error:
      
      wlcore: ERROR timeout waiting for the hardware to complete initialization
      
      And then wlcore is unable to reconnect until after the wlcore related modules
      are reloaded.
      
      Let's fix this by moving pm_runtime_put() earlier before we restart the hardware.
      And let's use the sync version to make sure we're done before we restart.
      
      Note that we still will get -EBUSY warning from wl12xx_sdio_set_power() but let's
      fix that separately once we know exactly why we get the warning.

      wlcore: Fix misplaced PM call for scan_complete_work() · 3ebbabea
      Tony Lindgren authored
      With runtime PM enabled, we now need to have wlcore enabled longer
      until after we're done calling wlcore_cmd_regdomain_config_locked():
      
      scan_complete_work()
       wlcore_cmd_regdomain_config_locked()
         wlcore_cmd_send_failsafe()
           wl12xx_sdio_raw_read()
      
      Note that this is not needed before runtime PM support as the
      custom PM code had it's own timer. We have not yet enabled runtime
      PM autosuspend for wlcore and this is why this issue now shows up.
      
      Let's fix the issues first before we enable runtime PM autosuspend.

      wlcore: Add support for runtime PM · fa2648a3
      Tony Lindgren authored
      We can update wlcore to use PM runtime by adding functions for
      wlcore_runtime_suspend() and wlcore_runtime_resume() and replacing
      calls to wl1271_ps_elp_wakeup() and wl1271_ps_elp_sleep() with calls
      to pm_runtime_get_sync() and pm_runtime_put().
      
      Note that the new wlcore_runtime_suspend() and wlcore_runtime_resume()
      functions are based on simplified versions of wl1271_ps_elp_sleep() and
      wl1271_ps_elp_wakeup().
      
      We don't want to use the old functions as we can now take advantage of
      the runtime PM usage count. And we don't need the old elp_work at all.
      And we can also remove WL1271_FLAG_ELP_REQUESTED that is no longer needed.
      
      Pretty much the only place where we are not just converting the existing
      functions is wl1271_op_suspend() where we add pm_runtime_put_noidle()
      to keep the calls paired.
      
      As the next step is to implement runtime PM autosuspend, let's not add
      wrapper functions for the generic runtime PM calls. We would be getting
      rid of any wrapper functions anyways.
      
      After autoidle we should be able to start using Linux generic wakeirqs
      for the padconf interrupt.

      wlcore: Make sure PM calls are paired · 02edf813
      Tony Lindgren authored
      The call to wl1271_ps_elp_wakeup() in wl12xx_queue_recovery_work() is
      unpaired. Let's remove it and add paired calls to wl1271_recovery_work()
      instead in preparation for changing things to use runtime PM.

      wlcore: Add missing PM call for wlcore_cmd_wait_for_event_or_timeout() · 4ec7cece
      Tony Lindgren authored
      Otherwise we can get:
      
      WARNING: CPU: 0 PID: 55 at drivers/net/wireless/ti/wlcore/io.h:84
      
      I've only seen this few times with the runtime PM patches enabled
      so this one is probably not needed before that. This seems to
      work currently based on the current PM implementation timer. Let's
      apply this separately though in case others are hitting this issue.
