* ath9k: improve BT FTP/PAN performanceRajkumar Manoharan2012-06-061-0/+4
| | | | | | | | | | | When BT FTP/PAN transmits while WLAN is idle, the one of 9462 chain often picks up BT's tx signal and starts receiving. If the current weight is set to be higher than BT tx, BT tx will be aborted and this also degrades BT performance. Hence lower WLAN rx priority in this case only when there are no WLAN traffic.

* ath9k_hw: remove ATH_BTCOEX_CFG_MCIRajkumar Manoharan2012-04-231-1/+0
| | | | | | | | | | | AR9462 uses modified version of 3-Wire hw scheme for btcoex. MCI itself is not a separate hw scheme but it aids to manage multiple bt profiles. In ar9462, bt priority traffic is identified by the number of bt profile types instead of gpio. So that this patch removes MCI hw scheme.

* ath9k: Cleanup MCI init/deinit routinesSujith Manoharan2012-02-271-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: move driver core helpers to main.cLuis R. Rodriguez2009-10-071-3/+4
| | | | | | | | | | | | | | | | | | Keep on btcoex.c only hardware access helpers, move the driver core specific code to main.c. To accomplish this we had to split ath_init_btcoex_info() into two parts, the driver core part -- ath_init_btcoex_timer() and the hw specific part -- ath9k_hw_init_btcoex_hw_info(). This highlights how ath_gen_timer is part of the driver core, not hw related, so stuff that into ath_btcoex struct. The ath9k_hw_btcoex_init() code is now put inline on ath_init_softc() through a switch to it easier to follow, since we did that we can now call ath_tx_get_qnum() from the main.c instead of btcoex.c Signed-off-by: Luis R.
