2015-05-09ath9k: Skip malformed frames on normal FFT reportNick Kossifidis1-32/+62
Since we have lots of frames on a normal FFT report don't bother processing the malformed ones. Only try to fix malformed frames in case of a short FFT report (only a single frame on the report). Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-05-09ath9k: Support processing of multiple FFT frames per report.Nick Kossifidis1-30/+237
Since we can identify the FFT frames on the report by checking the consistency of their magnitude info, we can process all of them, even when some of them are corrupted. This patch introduces two functions to quickly verify the integrity of the mag_info fields and some further tweaks to detect the frames in the report and process them. Note that in case of missing bytes we don't duplicate them, instead we leave them as zeroes. This way we get less noise on the FFT plot.

2015-05-09ath9k: Fix hanlding of maximum magnitude indexNick Kossifidis2-9/+27
Maximum magnitude index is a 5bit signed integer, convert to an 8bit signed integer and then "shift" it so that it can be used as an array index. Note that the current implementation adds +1 to the index value (so it can't be used as an array index) and it's only valid for HT20 channels. Note that the maximum magnitude index is not being used by the userspace tools that parse FFT samples (they just use maximum magnitude) so this doesn't break userspace compatibility.

commit 330b4e4be937 ("brcmfmac: Add wowl support for SDIO devices.") changed the behaviour by removing the MMC_PM_KEEP_POWER flag for non-wowl scenario, which needs to be restored. Another necessary change is to mark the card as being non-removable.

The driver was constructing a list of channels per wiphy band by querying the device. This list is not what the hardware is able to do as it is already filtered by the country setting in the device. As user-space may change the country this would require updating the channel list which is not recommended [1]. This patch introduces a superset of channels. The individual channels are disabled appropriately by querying the device.
