The QCA6174 in combination with new wmi-tlv firmware is capable of
multi-channel, beamforming, tdls and other features.
This patch just makes it possible to boot these devices and do some basic stuff
like connect to an AP without encryption. Some things may not work or may be
unreliable. New features will be implemented later. This will be addressed
eventually with future patches.

Add per station debugfs files when a station is added to mac80211's
station list. This helps to group peer specific debugfs entries
altogether. Right now this callback adds support to test aggregation
procedures (addba/addba_resp/delba) manually.
To enable automatic aggregation in target,
echo 0 >/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/
stations/XX:XX:XX:XX:XX:XX/aggr_mode
For manual mode,
echo 1 >/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/
stations/XX:XX:XX:XX:XX:XX/aggr_mode

Thermal cooling device support is added to control the temperature
by throttling the data transmission for the given duration. Throttling
is done using hw MAC quiet time setting. Period, duration and offset
from TBTT can be set up to quiet the MAC transmits for the required duty
cycle (% of quiet duration). The thermal device allows user to configure
duty cycle.
The quiet params are derived as follows.
period = max(25TU, beacon interval / number of bss)
duration = period * duty cycle / 100
Quiet mode can be disabled by setting the duty cycle to 0. The cooling
device can be found under /sys/class/thermal/cooling_deviceX/.
Corresponding soft link to this device can be found under phy folder.
/sys/class/ieee80211/phy*/device/cooling_device.
To set duty cycle as 40%,
echo 40 >/sys/class/ieee80211/phy*/device/cooling_device/cur_state

Latest main firmware branch introduced a new WMI
ABI called wmi-tlv. It is not a tlv strictly
speaking but something that resembles it because
it is ordered and may have duplicate id entries.
This prepares ath10k to support new hw.

Add testmode interface for starting and using UTF firmware which is used to run
factory tests. This is implemented by adding new state ATH10K_STATE_UTF and user
space can enable this state with ATH10K_TM_CMD_UTF_START command. To go back to
normal mode user space can send ATH10K_TM_CMD_UTF_STOP.

Adds the spectral scan feature for ath10k. The spectral scan is triggered by
configuring a mode through a debugfs control file. Samples can be gathered via
another relay debugfs file.
Essentially, to try it out:
ip link set dev wlan0 up
echo background > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
echo trigger > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
iw dev wlan0 scan
echo disable > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
cat /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan0 > samples
This feature is still experimental. Based on the original RFC patch of
Sven Eckelmann.

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:
