Subject: [PATCH 04/13] ath10k: add debugfs support to get per peer tids log
 via tracing

This patch provides support to get per peer tids log.

echo 1 > /sys/kernel/debug/ieee80211/phyX/netdev\:wlanX/stations/
XX:XX/peer_debug_trigger

These logs will be the part of FWLOGS which we collect the logs
via tracing interface. Here we will get the peer tigd logs only
once(not repeatedly) when we write 1 to the debugfs file.

Subject: [PATCH 05/13] ath10k: fix boot failure in UTF mode/testmode

Rx filter reset and the dynamic tx switch mode (EXT_RESOURCE_CFG)
configuration are causing the following errors when UTF firmware
is loaded to the target.

Error message 1:
[ 598.015629] ath10k_pci 0001:01:00.0: failed to ping firmware: -110
[ 598.020828] ath10k_pci 0001:01:00.0: failed to reset rx filter: -110
[ 598.141556] ath10k_pci 0001:01:00.0: failed to start core (testmode): -110

Error message 2:
[ 668.615839] ath10k_ahb a000000.wifi: failed to send ext resource cfg command : -95
[ 668.618902] ath10k_ahb a000000.wifi: failed to start core (testmode): -95

Avoiding these configurations while bringing the target in
testmode is solving the problem.

Subject: [PATCH 06/13] ath10k: fix reading sram contents for QCA4019

With QCA4019 platform, SRAM address can be accessed directly from host but
currently, we are assuming sram addresses cannot be accessed directly and
hence we convert the addresses.

While there, clean up growing hw checks during conversion of target CPU
address to CE address. Now we have function pointer pertaining to different
chips.

Subject: [PATCH 07/13] wcn36xx: Implement cancel_hw_scan

In the even that the wcn36xx interface is brought down while a hw_scan
is active we must abort and wait for the ongoing scan to signal
completion to mac80211.

Subject: [PATCH 09/13] ath9k_hw: check if the chip failed to wake up

In an RFC patch, Sven Eckelmann and Simon Wunderlich reported:

"QCA 802.11n chips (especially AR9330/AR9340) sometimes end up in a
state in which a read of AR_CFG always returns 0xdeadbeef.
This should not happen when when the power_mode of the device is
ATH9K_PM_AWAKE."

Include the check for the default register state in the existing MAC
hang check.

Subject: [PATCH 10/13] ath9k: fix race condition in enabling/disabling IRQs

The code currently relies on refcounting to disable IRQs from within the
IRQ handler and re-enabling them again after the tasklet has run.

However, due to race conditions sometimes the IRQ handler might be
called twice, or the tasklet may not run at all (if interrupted in the
middle of a reset).

This can cause nasty imbalances in the irq-disable refcount which will
get the driver permanently stuck until the entire radio has been stopped
and started again (ath_reset will not recover from this).

Instead of using this fragile logic, change the code to ensure that
running the irq handler during tasklet processing is safe, and leave the
refcount untouched.
