* ath9k: add TX99 supportLuis R. Rodriguez2013-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TX99 support enables Specific Absorption Rate (SAR) testing. SAR is the unit of measurement for the amount of radio frequency(RF) absorbed by the body when using a wireless device. The RF exposure limits used are expressed in the terms of SAR, which is a measure of the electric and magnetic field strength and power density for transmitters operating at frequencies from 300 kHz to 100 GHz. Regulatory bodies around the world require that wireless device be evaluated to meet the RF exposure limits set forth in the governmental SAR regulations. In the examples below, for more bit rate options see the iw TX bitrate setting documentation: http://wireless.kernel.org/en/users/Documentation/iw#Modifying_transmit_bitrates Example usage: iw phy phy0 interface add moni0 type monitor ip link set dev moni0 up iw dev moni0 set channel 36 HT40+ iw set bitrates mcs-5 4 echo 10 > /sys/kernel/debug/ieee80211/phy0/ath9k/tx99_power echo 1 > /sys/kernel/debug/ieee80211/phy0/ath9k/tx99 Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: Luis R.

* ath9k_hw: Improve fast channel change for AR9003 chipsRajkumar Manoharan2011-10-14
| | | | | | | | | | | | | | | | | In order to reduce the overall scan time, fast channel change should be implemented properly. This patch adds fast channel change support across band switch or channel mode switch instead of doing full chip reset. During the fastcc, tx iqcal measurements are preserved and will be reloaded after successful the channel change. This patch also addressed fast channel issue where the STA can not see APs in higher than operating channel on 5GHz band after the association.

* ath9k_hw: fix setting the hardware diversity flagFelix Fietkau2011-09-19
| | | | | | | | | | ath9k_hw_set_diversity is only called from init.c where it cannot affect the hardware setting because it's cleared on the next reset. Instead of using a PHY op for something that's supposed to be initialized statically, set the register value directly in the INI override function.

* ath9k: fix powersave frame filtering/buffering in AP modeFelix Fietkau2011-04-19
| | | | | | | | | | | | | | | | | | This patch fixes a long standing issue of pending packets in the queue being sent (and retransmitted many times) to sleeping stations. This was made worse by aggregation through driver-internal retransmitting of A-MDPU subframes. Previously the hardware tx filter was cleared unconditionally for every single packet - with this patch it uses the IEEE80211_TX_CTL_CLEAR_PS_FILT for unaggregated frames. A sta_notify driver op is added to stop aggregation for stations when they enter powersave mode. Subframes stay buffered inside the driver, to ensure that the BlockAck window keeps a sane state. Since the driver uses software aggregation, the clearing of the tx filter needs to be handled by the driver instead of mac80211 for aggregated frames.

* ath9k_hw: remove baseband rfsilent supportFelix Fietkau2010-12-20
| | | | | | | | | | | When rfkill is enabled, ath9k_hw unnecessarily configured the baseband to turn off based on GPIO input, however that code was hardcoded to GPIO 0 instead of ah->rfkill_gpio. Since ath9k uses software rfkill anyway, this code is completely unnecessary and should be removed in case anything else ever uses GPIO 0.

* ath9k_hw: clean up calibration flagsFelix Fietkau2010-10-06
| | | | | | | | | | | | | | The calibration actual calibration flags are only used by the per chip family source files, so it makes more sense to define them in those files instead of globally. That way the code has to test for less flags. Also instead of using a separate callback for testing whether a particular calibration type is supported, simply adjust ah->supp_cals in the calibration init which is called right after the hardware reset, before any of the calibrations are run.

* ath9k: merge noisefloor load implementationsFelix Fietkau2010-07-12
| | | | | | | | | | | | | | | | | AR5008+ and AR9003 currently use two separate implementations of the ath9k_hw_loadnf function. There are three main differences: - PHY registers for AR9003 are different - AR9003 always uses 3 chains, earlier versions are more selective - The AR9003 variant contains a fix for NF load timeouts This patch merges the two implementations into one, storing the register array in the ath_hw struct. The fix for NF load timeouts is not just relevant for AR9003, but also important for earlier hardware, so it's better to just keep one common implementation.

* ath9k_hw: inform ANI calibration when scanningLuis R. Rodriguez2010-06-14
| | | | | | | | | | | The new ANI implementation will use this to skip ANI calibration upon a scan.

* ath9k_hw: allow for spliting up ANI operations by familyLuis R. Rodriguez2010-06-14
| | | | | | | | | | | | The AR9003 hardware family will use a slightly modified ANI implementation which has not yet been tested on the other hardware families. To allow for this new ANI implementation a few ANI calls need to be abstracted away. This patch just allows for each hardware family to declare their own ANI ops and annotates the current ANI implementation as old. Signed-off-by: Luis R.

* ath9k_hw: split calib code by hardware familiesLuis R. Rodriguez2010-04-16
| | | | | | | | | | | | | | | | Calibration code touches phy registers and since these change the calibration code needs to be abstracted. Noise floor calibration is the only thing remaining but since the remaining calls only touch the AR_PHY_AGC_CONTROL register we'll just define that register conditionally, that will be done separately. The goal is to remove the dependency of ar9002_phy.h on calib.c This also adds stubs to be filled for AR9003 calibration code. Signed-off-by: Luis R.

* ath9k_hw: Move some RF ops to the private callbacksLuis R. Rodriguez2010-04-16
| | | | | | | | | | | | | | The PHY split is easier done in a few steps. First move the RF ops to the private ops and rename them accordingly. We split PHY stuff up first for the AR5008 and AR9002 families. There are some callbacks that AR9002 share with the AR5008 familiy so we set those first, if AR9002 has some different callbacks it will override them upon hardware init.
