Michal Kazior 8865bee483 ath10k: detect the number of spatial streams supported by hw
Until now ath10k assumed 3 spatial streams.
However some devices support only 2 spatial
streams.

This patch improves performance on devices that
don't support 3 spatial streams.

Michal Kazior affd321733 ath10k: implement device recovery
Restart the hardware if FW crashes.

If FW crashes during recovery we leave the
hardware in a "wedged" state to avoid recursive
recoveries.

When in "wedged" state userspace may bring
interfaces down (to issue stop()) and then bring
one interface (to issue start()) to reload
hardware manually.

Michal Kazior 293850575d ath10k: store firmware files in memory
Different FW versions may provide different
functions thus mean different hw capabilities
advertised to mac80211.

It is safe to swap firmware files on disk during
driver/device runtime without worries.

Michal Kazior 8cd13cad1c ath10k: decouple suspend code
Split up fw-related and hw-related suspension code.

Although we don't advertise WoW support to
mac80211 yet it's useful to keep the code in
suspend/resume hooks.

At this point there's no need to keep pci pm ops.
In case of WoW mac80211 calls ath10k_suspend()
which should take care of entering low-power mode.
In case WoW is not available mac80211 will go
through regular interface teradown and use start/stop.

Michal Kazior f7843d7f1a ath10k: allow deferred regd update
Regulatory domain notification hook can be called
regardless of the hw state (i.e. before start
mac80211 callback).

Michal Kazior dd30a36e11 ath10k: decouple core start/stop logic
Enables code reuse for proper hw reconfiguration
that is in turn required for proper
suspend/hibernation/wowlan support.

Kalle Valo 5e3dd157d7 ath10k: mac80211 driver for Qualcomm Atheros 802.11ac CQA98xx devices
Here's a new mac80211 driver for Qualcomm Atheros 802.11ac QCA98xx devices.
A major difference from ath9k is that there's now a firmware and
that's why we had to implement a new driver.

The wiki page for the driver is:

http://wireless.kernel.org/en/users/Drivers/ath10k

The driver has had many authors, they are listed here alphabetically:
