* ath9k: Remove ATH9K_HW_CAP_MCI checksSujith Manoharan2012-02-27
| | | | | | | | With the ability to remove BTCOEX support at compile time, these checks are no longer needed. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k: Cleanup MCI init/deinit routinesSujith Manoharan2012-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch simplifies the buffer allocation functions for MCI and removes unneeded memset calls. Also, a couple of unused variables are removed and a memory leak in DMA allocation is fixed.

* ath9k_hw: make bluetooth coexistence support optional at compile timeFelix Fietkau2011-12-19
| | | | | | | | | | | | | | | | 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 <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath: Convert ath_dbg(bar, ATH_DBG_<FOO>, to ath_dbg(bar, FOOJoe Perches2011-12-19
| | | | | | | | | | | | | | 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.

* ath9k: Add btcoex profile management support for AR9462Rajkumar Manoharan2011-11-08
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.
