- ath9k: Fix crash in MCC mode
-
- When a channel context is removed, the hw_queue_base
- is set to -1, this will result in a panic because
- ath9k_chanctx_stop_queues() can be called on an interface
- that is not assigned to any context yet - for example,
- when trying to scan.
-
- Fix this issue by setting the hw_queue_base to zero
- when a channel context is removed.

- ath9k: Fix flushing in MCC mode
-
- When we are attempting to switch to a new
- channel context, the TX queues are flushed, but
- the mac80211 queues are not stopped and traffic
- can still come down to the driver.
-
- This patch fixes it by stopping the queues
- assigned to the current context/vif before
- trying to flush.

-
- ath9k: Fix queue handling for channel contexts
-
- When a full chip reset is done, all the queues
- across all VIFs are stopped, but if MCC is enabled,
- only the queues of the current context is awakened,
- when we complete the reset.
-
- This results in unfairness for the inactive context.
- Since frames are queued internally in the driver if
- there is a context mismatch, we can awaken all the
- queues when coming out of a reset.
-
- The VIF-specific queues are still used in flow control,
- to ensure fairness when traffic is high.

- ath9k_hw: fix PLL clock initialization for newer SoC
-
- On AR934x and newer SoC devices, the layout of the AR_RTC_PLL_CONTROL
- register changed. This currently breaks at least 5/10 MHz operation.
- AR933x uses the old layout.
-
- It might also have been causing other stability issues because of the
- different location of the PLL_BYPASS bit which needs to be set during
- PLL clock initialization.
-
- This patch also removes more instances of hardcoded register values in
- favor of properly computed ones with the PLL_BYPASS bit added.

- ath9k_hw: reduce ANI spur immunity setting on HT40 extension channel
-
- The cycpwr_thr1 value needs to be lower on the extension channel than on
- the control channel, similar to how the register settings are programmed
- in the initvals.
-
- Also drop the unnecessary check for HT40 - this register can always be
- written. This patch has been reported to improve HT40 stability and
