* ath5k: no need to save/restore the default antennaBruno Randolf2010-06-08
| | | | | | | | | Since ath5k_hw_set_antenna_mode() always writes the default antenna register and is called at the end of reset, there is no need to separately save and restore the default antenna.

* ath5k: new function for setting the antenna switch tableBruno Randolf2010-06-08
| | | | | | | | | | | | | | | | | | | Collect all pieces concering the antenna switch table into one function. Previously it was split up between ath5k_hw_reset() and ath5k_hw_commit_eeprom_settings(). Also we need to set the antenna switch table when ath5k_hw_set_antenna_mode() is called manually (by "iw phy0 antenna set", for example). I'm not sure if we need to set the switchtable at the same place in ath5k_hw_reset() as it was before - it is set later thru ath5k_hw_set_antenna_mode() anyways - but i leave it there to avoid problems(?). Plus print switchtable registers in the debugfs file. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* ath5k: clarify logic when to enable spur mitigation filterBruno Randolf2010-06-02
| | | | | | | | | | | | | The old code logically did not make sense and seems to have been confused by the fact that we could have newer EEPROMs on older hardware. In any case the spur mitigation filter was set if the srev was >= AR5K_SREV_AR5424. Spur info is available only from EEPROM versions bigger than 5.3 but but the EEPOM routines will use static values for older versions, so that should be o.k.

* drivers/net: Remove unnecessary returns from void function()sJoe Perches2010-05-14
| | | | | | | | | | | | | | | | | | | | | | This patch removes from drivers/net/ all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand.

| | | | | | | | | | | | | | | | | | | | ath5k_hw_register_timeout() was duplicated between phy.c and reset.c.

* | ath5k: read eeprom IQ calibration values correctly for G modeBruno Randolf2010-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | we read the IQ correction values (i_cal and q_cal) for G mode from a wrong location (the same shifts as for A mode is applied which is incorrect). use correct locations, matching the docs and HAL sources. also we should write IQ correction only when we have that information in the EEPROM, starting from version 4. also write it in the same way as we do in the periodic recalibration (enable last), just to be sure.

* ath5k: dont use external sleep clock in AP modeBob Copeland2010-01-22
| | | | | | | | | | | | | When using the external sleep clock in AP mode, the TSF increments too quickly, causing beacon interval to be much lower than it is supposed to be, resulting in lots of beacon-not-ready interrupts.

* ath5k: Implement mac80211 callback set_coverage_classLukáš Turek2010-01-12
| | | | | | | | | | The callback sets slot time as specified in IEEE 802.11-2007 section 17.3.8.6 (for 20MHz channels only for now) and raises ACK and CTS timeouts accordingly. The values are persistent, they are restored after device reset. Signed-off-by: Lukas Turek <8an@praha12.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath5k: Reimplement clock rate to usec conversionLukáš Turek2010-01-12
| | | | | | | | | | | | | | | The original code was correct in 802.11a mode only, 802.11b/g uses different clock rates. The new code uses values taken from FreeBSD HAL and should be correct for all modes including turbo modes. The former rate calculation was used by slope coefficient calculation function ath5k_hw_write_ofdm_timings. However, this function requires the 802.11a values even in 802.11g mode. Thus the use of ath5k_hw_htoclock was replaced by hardcoded values. Possibly the slope coefficient calculation is not related to clock rate at all.

* ath5k: use noise calibration from madwifi halBob Copeland2009-10-27
| | | | | | | | | | | | | | | | | This updates ath5k to calibrate the noise floor similar to the way it is done in the madwifi hal and ath9k. Of note: - we start NF measurement at the same time as AGC calibration, but do not actually read the value until the periodic (long) calibration - we keep a history of the last few values read and write the median back to the hardware for CCA - we do not complain if NF calibration isn't complete, instead we keep the last read value.

* atheros: use get_unaligned_le*() for bssid mask settingLuis R. Rodriguez2009-10-07
| | | | | | | | | | | | | | | | | Historically some macro helpers have been users for this, AR5K_LOW_ID() and AR5K_HIGH_ID(), use upstream unaligned helpers instead. This applid to ath5k and ar9170. ath9k already uses this. Worth noting is ath5k uses an ah_sta_id but that is already the MAC address combined with the associaiton ID, ah_sta_id is really ETH_ALEN in size.

All rfkill related code is separated into newly created rfkill.c.

I also switched between various tx power levels and i saw an equal power change on the remote machine (so txpower changes as expected) and verified that we have the same output on each rate.
