2011-12-19ath9k_hw: make bluetooth coexistence support optional at compile timeFelix Fietkau1-0/+9
Many systems (e.g. embedded systems) do not have wifi modules connected to bluetooth modules, so bluetooth coexistence is irrelevant there. With the addition of MCI support, ath9k picked up quite a bit of extra code that can be compiled out this way. This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for querying the bluetooth coexistence scheme, allowing the compiler to eliminate code that uses it, with only very little use of #ifdef. On MIPS this reduces the total size for the modules by about 20k. Signed-off-by: Felix Fietkau <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2011-12-19ath: Convert ath_dbg(bar, ATH_DBG_<FOO>, to ath_dbg(bar, FOOJoe Perches1-6/+4
Add ATH_DBG_ to macros to shorten the uses and reduce the line count. Coalesce ath_dbg formats. Add missing spaces to coalesced formats. Add missing newline terminations to ath_dbg formats. Align ath_dbg arguments where appropriate. Standardize ath_dbg formats without periods. Signed-off-by: Joe Perches <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2011-11-17ath9k: Remove enabling btcoex from stomp type changeRajkumar Manoharan1-0/+2
This patch removes btcoex_enable from stomp type change and let it be called from callee functions that makes the code can be reusable for MCI changes. Signed-off-by: Rajkumar Manoharan <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2011-11-08ath9k: Add btcoex profile management support for AR9462Rajkumar Manoharan1-3/+4
AR9462 chips have the capabilities to provoide bluetooth profile information. For non-AR9462 btcoex chips, the BT priority traffic was identified by periodically polling the respective registers and updated dutycycle, stomptype, etc. As AR9462 chip offers the BT profile informations, let us make use of that to update aggregation limit, dutycycle, stomptype and wieghtages.

2011-08-09ath9k: do not enable interrupt on set interrupt maskRajkumar Manoharan1-0/+2
At preset set_interrupt also enables interrupt after changing mask. This is not necessary in all cases and also sometime it breaks the assumption that interrupt was disabled. So let us enable the interrupt explicity if it was disabled earlier. This could also avoid unnecessary register ops and also helps the follow up patch to have global ref count for interrupts ops.

2011-04-25ath9k: Fix LED gpio for AR93xx chipsets.Senthil Balasubramanian1-0/+2
The LED gpio is incorrectly programmed for AR9300 and so the led is not working propelry. AR93xx uses gpio 10 for LED and not the default. Signed-off-by: Senthil Balasubramanian <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2011-04-25ath9k: Fix bug in configuring hw timerVasanthakumar Thiagarajan1-3/+3
Hw next tigger time is configured as current_tsf + (timer_period * 10) which is wrong, it should be current_tsf + timer_period. The wrong hw timer configuration would cause btcoex related issues.

2010-11-09ath9k: remove a redundant call to ath9k_hw_gettsf32Felix Fietkau1-4/+2
When the timer_next argument to ath9k_gen_timer_start is behind the tsf value, tsf + timer_period is used, which is what ath_btcoex_period_timer was setting it to. Signed-off-by: Felix Fietkau <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2010-11-09ath9k_hw: optimize interrupt mask changesFelix Fietkau1-2/+2
OProfile showed that ath9k was spending way too much time in ath9k_hw_set_interrupts. Since most of the interrupt mask changes only need to globally enable/disable interrupts, it makes sense to split this part into separate functions, replacing all calls to ath9k_hw_set_interrupts(ah, 0) with ath9k_hw_disable_interrupts(ah). ath9k_hw_set_interrupts(ah, ah->imask) only gets changed to ath9k_hw_enable_interrupts(ah), whenever ah->imask was not changed since the point where interrupts were disabled.
