Cover letter [ath9k-devel] [PATCH 0/3] Refactoring spectral scan code and adding spectral scan support for ath9k_htc

Hm... it compiles but i didn't go any results with my script:

sudo bash -c "echo chanscan > /sys/kernel/debug/ieee80211/phy1/ath9k_htc/spectral_scan_ctl" sudo bash -c "echo 8 > /sys/kernel/debug/ieee80211/phy1/ath9k_htc/spectral_count"

for i in $(seq 1 44); do
sudo iw dev wlan-test scan
sleep 1
done

sudo bash -c "cat /sys/kernel/debug/ieee80211/phy1/ath9k_htc/spectral_scan0 > /tmp/fft_results"
sudo bash -c "echo 8 > /sys/kernel/debug/ieee80211/phy1/ath9k_htc/spectral_count"

sudo bash -c "echo disable > /sys/kernel/debug/ieee80211/phy1/ath9k_htc/spectral_scan_ctl"

./fft_eval /tmp/fft_results

The patches move the common components of spectral scan funcationality to common-spectral.c.
Also added spectral scan support to ath9k_htc using the same mechanism to collect spectral scan data as used by ath9k driver.
This work was done at the Wisconsin Wireless and NetworkinG Systems (WiNGS) Lab at the University of Wisconsin Madison.
Ashish Patro (3):
Moving the ath9k specific spectral functions to ath9k.h from
spectral.h. Renamed spectral.h to common-spectral.h
Refactoring the ath9k driver to move common spectral functions to
common-spectral.c
Update spectral scan calls to support both ath9k and ath9k_htc.
Adding spectral scan functionality to ath9k_htc driver. Tested using a AR9271 WiFi card.
