2014-01-04ath9k: Handle unsupported MAC versions earlySujith Manoharan1-24/+24
There is no point in trying to bring up the chip when the MAC version is not present in the supported list. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-01-04ath9k: Fix "cc_lock" usageSujith Manoharan2-9/+7
IRQ save/restore is not required for the cycle counters since they are accessed only from softirq and process context. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-01-04ath9k: Process BB watchdog events in the taskletSujith Manoharan1-8/+6
Move the BB processing code to the tasklet and avoid doing it in the ISR, there is no real benefit and this makes the ISR less heavy. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-01-04ath9k: Remove RX PollSujith Manoharan7-77/+17
This patch removes the convoluted and hacky method of monitoring for connectivity. We rely on mac80211's connection loss logic and doing it in the driver is not necessary. The HW check for MAC/BB hangs is also simplified, there is no need to have a separate work instance for it. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-01-04ath9k: Fix baseband watchdog resetSujith Manoharan1-8/+19
Do a HW reset only for required signatures. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-01-04ath9k: Identify baseband watchdog signaturesSujith Manoharan3-0/+65
A full HW reset is not required for all baseband watchdog signatures. Some BB watchdog updates are benign and can be discarded, some require re-programming of certain registers and others require a chip reset. This patch adds a routine to identify such signatures. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-01-04ath9k: Fix baseband watchdog interruptsSujith Manoharan3-6/+27
Program the required baseband watchdog interrupt mask to ensure that the correct watchdog interrupts are raised when the BB is hung for some reason. Also, use the capability HW_BB_WATCHDOG instead of relying on other flags. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-01-04ath9k: Fix PHY restart workaroundSujith Manoharan2-11/+11
The PHY restart workaround that handles baseband hangs for packets with unsupported rates is required only for a HW bug in AR9300 v2.2. All the subsequent chips in the AR9003 family do not require this driver fix since it has been addressed in the HW. Since the value of the AR_PHY_RESTART register is written with the default initvals, make sure that PHY restart is always disabled once this particular BB hang signaure has been encountered.

2014-01-04ath9k: Fix MAC HW hang check for AR9003Sujith Manoharan1-55/+75
The current method of identifying MAC hangs is convoluted and also, the signatures are wrong and don't apply to all the chips in the AR9003 family. Fix this by cleaning up the code and checking for the correct hang signatures. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-01-04ath9k: Add HW callbacks for MAC/BB hang checksSujith Manoharan4-70/+85

2014-01-04ath9k: Register supported HW hang checksSujith Manoharan5-9/+59
HW hang checks have to be done on a per-chip basis. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-01-04ath9k: Fix max AMPDU size calculationSujith Manoharan2-13/+2
The maximum A-MPDU size is calculated in ath_tx_aggr_start(), so there is no need to do it in node_attach() too. Also, make sure that the correct size is calculated as described in 8.4.2.58.3.

2014-01-04ath9k_hw: fix TSF offset calculationFelix Fietkau1-2/+2
Since the unit is microseconds and not milliseconds, tv_sec needs to be multiplied by 1000000, not 1000. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-01-04ath9k_hw: fix gentimer callback without overflow handlerFelix Fietkau1-2/+2

2013-12-19ath9k: simplify/fix tx packet TID handlingFelix Fietkau1-8/+1

2013-12-19ath9k: fix TSF offset precision issueFelix Fietkau1-3/+4
Dividing the beacon interval by ATH_BCBUF (8) truncates the result for the default beacon interval of 100. Fix the calculation by moving the division after conversion from TU to microseconds. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2013-12-19ath9k: Add a delay between RTC reset/clear for AR9003Sujith Manoharan1-2/+1
The small delay that is present between a RTC reset/clear operation is required for the chip to settle and this is needed for all chips, not just the AR9002 family. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-12-19ath9k: Fix regulatory complianceSujith Manoharan2-1/+35

2013-12-19ath9k: properly preserve TSF across resetFelix Fietkau2-45/+45
The beacon code previously reset TSF on every configuration call, as some of the code was not prepared to properly calculate nexttbtt based on current TSF. This patch adds a common function for calculating nexttbtt and moves the TSF reset to driver start. This should improve AP mode compatibility with various stations that expect the TSF to not randomly jump due to hardware resets. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2013-12-19ath9k_hw: clean up generic timer codeFelix Fietkau5-104/+45

2013-12-17ath9k: Fix interrupt handling for the AR9002 familySujith Manoharan1-9/+43
This patch adds a driver workaround for a HW issue. A race condition in the HW results in missing interrupts, which can be avoided by a read/write with the ISR register.
