2010-12-02Revert "ath9k: Fix STA disconnect issue due to received MIC failed bcast frames"John W. Linville
This reverts commit 916448e77f6bcaaa7f13c3de0c3851783ae2bfd0. "As far as I can tell, either of these patches breaks multiple VIF scenarios. I'm not sure exactly why, but I had to revert this to get any of my interfaces to associate." -- Ben Greear <greearb@candelatech.com> http://marc.info/?l=linux-wireless&m=129123368719339&w=2 Signed-off-by: John W.

2010-12-02ath9k_hw: fix more bitfield related endian issuesFelix Fietkau
A few LNA control related flags were also specified as a bitfields, however for some strange reason they were written in big-endian order this time. Fix this by using flags instead. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-12-02ath9k_hw: fix endian issues with CTLs on AR9003Felix Fietkau
Parsing data using bitfields is messy, because it makes endian handling much harder. AR9002 and earlier got it right, AR9003 got it wrong. This might lead to either using too high or too low tx power values, depending on frequency and eeprom settings. Fix it by getting rid of the CTL related bitfields entirely and use masks instead.

2010-12-02ath9k: Fix bug in reading input gpio state for ar9003Vasanthakumar Thiagarajan
The register which gives input gpio state is 0x404c for ar9003, currently 0x4048 is wrongly used. This will disable RF and make it unusable on some of AR9003. Cc:stable@kernel.org Signed-off-by: Vasanthakumar Thiagarajan <vasanth@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-11-30ath5k: Set turbo bit on rf bank 2Nick Kossifidis
* A diff between rfbuffer settings of turbo and non-turbo modes indicates there is a bit on bank 2 related to turbo operation (it's set on turbo modes). This bit is present on all radios except RF5413 that seems to have a completely different bank 2. Also since 2317 has the same rf-registers locations with 2425 and since the bit exists on 2317 I assume it also exists on 2425/2417). So in case we use turbo mode (40MHz) enable it on bank modification. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-11-30ath5k: Clean up turbo mode initvals/rfregsNick Kossifidis
* Clean up what's left of turbo mode, since we handle all register modifications (rfbuffer comes next) on code there is no need to have duplicated arrays. * Rename change_channel to skip_pcu on initvals.c as we did on reset.c Signed-off-by: Nick Kossifidis <micklfemm@gmail.com> Signed-off-by: John W.

2010-11-30ath5k: Skip tx power setting on AR5210 for nowNick Kossifidis
* Don't return -EINVAL when trying to set tx power on RF5110 because AR5210 reset will fail. We need to add support for RF5110 and AR5210 eeprom in the future but for now just skip it. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-11-30ath5k: No need to save/restore staid flags on resetNick Kossifidis
* Since we set antenna flags on phy init and ack bitrate mode on pcu init, there is no need to save/restore sta_id flags on ath5k_hw_reset. Also we don't need to re-set our mac address because it's not affected by resets. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-11-30ath5k: Support synth-only channel change for AR2413/AR5413Nick Kossifidis
* Add synth-only channel change for AR2413/5413. When we call ath5k_reset with a channel ath5k_hw_reset will first try to set channel on PHY while PHY is running instead of doing a normal full reset. To do this phy_init has to change to implement this functionality. * Clean up change_channel flag, what it really did was skip PCU registers when setting initvals. This is done because on reset PCU registers are not affected (except the registers we set in pcu init and -due to hw problems- TSF). Use a new skip_pcu flag that's not misleading instead. In the future we might use that to also skip PCU reset and save us the TSF etc problems (needs testing because standard practice is to reset everything). * Use fast channel change only when setting channel, and set skip_pcu to false only on init. When we reset the card due to DMA or PHY problems skip pcu but never do a fast channel change. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-11-30ath5k: Skip powertable setting when we are on the same channelNick Kossifidis

2010-11-30ath5k: Always set IFS intervals on resetNick Kossifidis
* Make sure we always set IFS timings even if no coverage class is set. If we don't we'll miss the needed changes for different bwmodes. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-11-30ath5k: Set all IFS intervals, not just slot timeNick Kossifidis
* Replace set_slot_time with set_ifs_intervals that also sets the various inter-frame space intervals based on current bwmode. * Clean up AR5210 mess from reset_tx_queue, AR5210 only has one data queue and we set IFS intervals for that queue on set_ifs_intervals so there is nothing left to do for 5210 on reset_tx_queue.

2010-11-30ath5k: Extend rate_durationNick Kossifidis
* Extend ieee80211_generic_frame_duration to support the various bwmodes. * Better document what's going on with ack bitrates and update write_rate_duration to support the standard ack bitrates (when we don't set the high bit). * Get rid of set_ack_bitrate_high and introduce a flag on ath5k_hw for this (we only called the function on init anyway so there is no difference).

2010-11-30ath5k: Extend get_default_sifs/slot_timeNick Kossifidis
* Extend get_default_sifs/slot_time to include timings for turbo half and quarter rate modes. * AR5210 code for now uses timings already on core clock units instead of usecs so rename them (we 'll clean it up later).

2010-11-30ath5k: Increase PHY settling parameters for turo modeNick Kossifidis
* On turbo mode increase PHY settling times, note that we only increase switch settling time on AR5212 as indicated by initvals. * A few cleanups: Move frame control settings for AR5210 from reset_tx_queue to tweak_initvals and remove phy_scal settings from tweak_initvals (we tweak them alread on set_sleep_clock).

2010-11-30ath5k: Small cleanup on tweak_initvalsNick Kossifidis
* Now that we properly set rx/tx latencies for AR5311 remove that old buggy part of code left inside ath5k_hw_tweak_initval_settings that was never executed (you can't have an RF5112 radio on a mac older than AR5212). Also use a magic value for 5311 PHY_SCAL value. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-11-30ath5k: Add new field on ath5k_hw to track bandwidth modesNick Kossifidis
* Prepare for half/quarter/turbo support, introduce a new ah_bwmode parameter and get rid of ah_turbo. Bwmode stands for "bandwidth mode" and can have 4 values, default (20MHz), turbo (40MHz), half rate (10MHz), and quarter rate (5MHz).

2010-11-30ath5k: Use new function to stop beacon queueNick Kossifidis
* Since we only use ath5k_hw_stop_tx_dma to stop the beacon queue, introduce a new function ath5k_hw_stop_beacon_queue so that we can use that instead and have better control. In the future we can add more beacon queue specific stuff there (maybe tweak beacon timers or something), for now just call ath5k_hw_stop_tx_dma. * Also since we don't call ath5k_hw_stop_rx/tx_dma from outside dma.c, make them static.

2010-11-30ath5k: Use DCU early termination correctlyNick Kossifidis
* DCU early termination should be used to quickly flush QCU according to docs so don't enable it for all queues, enable it only when stopping each queue and disable it when we are done. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-11-30ath5k: Debug DMA timeoutsNick Kossifidis

2010-11-30ath5k: Use new dma_stop function on base.cNick Kossifidis
* Since we stop rx/tx dma and pcu durring reset there is no need to call ath5k_hw_stop_rx/tx_dma before, also there is no need to call them durring stop_locked since we can use ath5k_hw_dma_stop for both.

2010-11-30ath5k: Stop PCU on resetNick Kossifidis
* Stop PCU receive logic (DRU) durring reset We need to be sure pcu is not active when trying to stop rx dma right now this is done on ath5k_reset (base.c) but later we are going to clean it up.

2010-11-30ath5k: Reset cleanup and generic cleanupNick Kossifidis
* No functional changes * Clean up reset: Introduce init functions for each unit and call them instead of having everything inside ath5k_hw_reset (it's just c/p for now so nothing changes except calling order -I tested it with various cards and it's ok-) * Further cleanups: ofdm_timings belongs to phy.c rate_duration belongs to pcu.c clock functions are general and belong to reset.c (more to follow) * Reorder functions for better organization: We start with helpers and other functions follow in categories, init functions are last Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

2010-11-30ath9k: Add support for Adaptive Power ManagementMohammed Shafi Shajakhan
This feature is to mitigate the problem of certain 3 stream chips that exceed the PCIe power requirements.An EEPROM flag controls which chips have APM enabled which is basically read from miscellaneous configuration element of the EEPROM header. This workaround will reduce power consumption by using 2 Tx chains for Single and Double stream rates (5 GHz only).All self generated frames (regardless of rate) are sent on 2 chains when this feature is enabled(Chip Limitation).
