wifi: ath11k: Add spectral scan support for 160 MHz There are two types of 160 MHz spectral scan support mentioned below 1. Fragmented approach 2. Single event approach In this fragmented approach, single 160 MHz will be split as two 80 MHz buffer. First fft sample buffer will contain spectral scan result of primary 80 MHz and the second fft sample buffer will contain secondary 80 MHz and here cfreq1 and cfreq2 will be mentioned. In case of 160 MHz on 36th channel will contain cfreq1 as 5210 and cfreq2 as 5290. Chipsets which support this approach are IPQ8074/IPQ6018. Replacing freq1 with freq2 in every secondary sepctral scan event to distinguish between two different 80 MHz spectral event data. In the 2nd approach each fft sample buffer will contain spectral scan result for whole 160 MHz by mentioning cfreq1 as 5250 which is center frequency of whole 160 MHz. Chipset which support this approach is QCN9074. Host will receive spectral event from target for every 5 fft samples.

ath11k: add support for spectral scan spectral scan control interface is exposed through debugfs eentry. Relayfs is used to collect the spectral data. These interfaces are similar to ath10k spectral. spectral debugfs interfaces are below, echo background > /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan_ctl echo trigger > /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan_ctl iw dev wlan0 scan echo disable > /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan_ctl cat /sys/kernel/debug/ieee80211/phy0/ath11k/spectral_scan0 > fft_samples.dump Tested-on: IPQ8074 WLAN.HK.2.1.0.1-01228-QCAHKSWPL_SILICONZ-1 Signed-off-by: Karthikeyan Periyasamy <periyasa@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/1591688014-26441-2-git-send-email-periyasa@codeaurora.org
