      ath9k: Fix power save usage count imbalance on deinit · c7c18060
      Rajkumar Manoharan authored
      While unloading the driver, the ps_usecount is incremented
      before configuring gpio registers in deinit_device.
      But it is failed to restore the ps_usecount after that.
      The problem is that the chip is forcibly moved to FULL SLEEP
      by radio_disable when mac80211 is reporting as idle
      though ps_usecount is not zero.
      
      This patch retores ps_usecount properly and ensures that
      the chip is always moved to full sleep only if ps usage
      count is zero which also helps in debugging deadbeef on
      multivif case. And also fixes the following warning.
      
      ath: DMA failed to stop in 10 ms AR_CR=0xdeadbeef AR_DIAG_SW=0xdeadbeef
      ath: Could not stop RX, we could be confusing the DMA engine when we
      start RX up

      ath9k_hw: Fix system hang when resuming from S3/S4 · 5b64aa72
      Rajkumar Manoharan authored
      The bit 6 & 7 of AR_WA (0x4004) should be enabled only
      for the chips that are supporting L0s functionality
      while resuming back from S3/S4.
      
      Enabling these bits for AR9280 is causing system hang
      within a few S3/S4-resume cycles.
