* ath9k: Initialize txgain and rxgain for newer AR9287 chipsets.Vivek Natarajan2009-09-23
| | | | | Signed-off-by: Vivek Natarajan <vnatarajan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k: Disable autosleep feature by default.Vivek Natarajan2009-09-23
| | | | | | | | | | Autosleep needs to be disabled for AR9287 chipsets also. Since autosleep is not used for any of the currently supported chipsets, disable it by default and can be enabled if needed for any of the future chipsets.

| | | | | | | | | | | This function currently does initialization + enable the btcoex support. Split it into two logical functions which does the above operations separately. Btcoex initialization is done during attach time and enabling this feature is done in start(). Also, add code to disable btcoex support in stop().

* ath9k: call ath9k_hw_detach() once upon hw init failureLuis R. Rodriguez2009-08-04
| | | | | | | | | | | | | | If hw initialization fails (ath9k_hw_init()) on ath_init_softc() we bail out and call ath9k_hw_detach(). The call ath9k_hw_detach() is conditional though as ath9k_hw_init() could itself have called ath9k_hw_detach(). Just describing this is itself a brain twister. Avoid this nonsense by removing ath9k_hw_detach() from ath9k_hw_init(). Upon hw initialization failure we expect the callers to take care of the cleanup. Signed-off-by: Luis R.

* ath9k: describe hw initialization betterLuis R. Rodriguez2009-08-04
| | | | | | | | | | During initialization ath9k tends to use "attach" to when we initialize hardware due to the fact we used to attach a "HAL". The notion of a HAL is long gone, so lets just be clear on what we are doing. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k: break up hw initialization into a few more helpersLuis R. Rodriguez2009-08-04

* ath9k: call hw initializer directlyLuis R. Rodriguez2009-08-04
| | | | | | | | | | ath9k_hw_attach() was going first through some device id verifier, and then calling some other helper which was doing the real hardware initialization.

* ath9k: fix race with IEEE80211_CONF_PS checksGabor Juhos2009-07-29
| | | | | | | | | | | | | | | There is a small window where the mac80211 changes the IEEE80211_CONF_PS flag, and then informs the driver about the change. We have a race condition if we are checking the flag in the same time. Avoid it by introducing a local variable, and using that instead of checking the IEEE80211_CONF_PS flag directly.
