ath9k_set_offchannel_state() would be a better place to do this,

in the AR9003 family, so this is done in the initvals.
ar9003_hw_apply_minccapwr_thresh() will be used only for chips which
contain the new 'MinCCApwr' field in struct ar9300_BaseExtension_1.
This is not present in almost all the AR9003-family chips. I believe it has
been introduced in AR955x.

is AR9331 which has new minCCApwr_thr values in the internal PCOEM driver,
but not in the SoC driver - not sure which one is correct.

Dear Sujith,
finally I found the real reason, ath3k fails to work approximately 2/3
of the time if btusb is connected to a pin which uses the xhci driver.
I compiled a dkms kernel package, with the help of a very nice
canonical employee, which switches the usb pin

The minimum CCA power threshold values have to be adjusted
for existing cards to be in compliance with new regulations.
Newer cards will make use of the values obtained from EEPROM,
support for this was added earlier. To make sure that cards

As long as it doesn't introduce any regression or behavioral change
in ath9k, they look good. :)

and I have not yet been able to reach 295Mbps of TCP throughput

By adjusting TCP parameters using sysctl or hacking the code ?

Calibration data is not reused for SoC chips, so
call ar9003_hw_tx_iq_cal_post_proc() with the correct
argument. The 'is_reusable' flag is currently used
only for PC-OEM chips, but it makes things clearer to
specify it explicity.

This series updates the IQ calibration code, fixing various
issues. There are still some more issues to be addressed.

ath9k: Fix IQ cal post processing for SoC
ath9k: Check explicitly for IQ calibration
ath9k: Rename
From: Sujith Manoharan c_man...@qca.qualcomm.com
In chips like AR955x, the initvals contain the information
whether IQ calibration is to be done in the HW when an
AGC calibration is triggered. Check if IQ-CAL is enabled
in the initvals before flagging 'txiqcal_done' as true.

Use ar9003_hw_tx_iq_cal_outlier_detection instead.

Incorrect values are programmed in the registers
containing the IQ correction coefficients by the IQ-CAL
post-processing code. Fix this.

This patch adds a routine to calculate the median IQ correction
values for AR955x, which is used for outlier detection.
The normal method which is used for all other chips is
bypassed for AR955x.
