* ath9k: add a helper to clean the core driver upon module unloadLuis R. Rodriguez2009-10-07
| | | | | | | | | | | The core driver needs to be stopped and then as a last step the hardware needs to be stopped and its structure free'd. We do this by moving the core driver cleanup to a new helper ath_clean_core() and have ath_cleanup() call it. Only as a last step does ath_cleanup() now free the hw. Signed-off-by: Luis R.

* ath9k: initialize hw prior to debugfsLuis R. Rodriguez2009-10-07
| | | | | | | | | | | debugfs uses the hardware for several debugfs files as such the hardware must be initialized and available prior to its usage. The same applies to when we free the hw structs -- free debufs file entries prior to free'ing the hardware. Reported-by: Vasanthakumar Thiagarajan <vasanth@atheros.com> Signed-off-by: Luis R.

* ath5k: enable Power-Save Polls by setting the association IDLuis R. Rodriguez2009-10-07
| | | | | | | | | | | | | mac80211 has long provided us the association ID. This isn't useful except for Power-Save polling which now gets enabled.

* ath5k: simplify passed params to ath5k_hw_set_associd()Luis R. Rodriguez2009-10-07
| | | | | | | | | | | We have access to common->curbssid and common->curaid so just use those. Note that common->curaid is always 0 so this keeps our current behaviour of always using 0 for now. Once we fix storing the association ID passed by mac80211 this will require no changes here. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

* ath9k: move hw code to its own moduleLuis R. Rodriguez2009-10-07
| | | | | | | | | | | | | | | | | hw code for Atheros 802.11n hardware is commmon between different chipsets. This moves this code into a separate module, the next expected user of this code will be the ath9k_htc module. The ath9k/ dir is now selected by ATH9K_HW, an option which gets selected by either ath9k or ath9k_htc, but remains invisible for user menuconfig configuration. If either ath9k or ath9k_htc will be compiled into the kernel ath9k_hw will also be compiled in. Cc: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: Luis R.

Conversely, if the current channel is 2484 MHz and if the channel is changing to one between 2412 and 2472 MHz, then the three registers need to be programmed to the "normal" values.

| | | | | | | | | | | | | | This was for supporting 25 MHz spacing for HT40, this is not used as we use 20 MHz spacing instead for HT40 as per 802.11n. The hardware is capable of it though so we leave the phymode definition and EEPROM parsing for it. If some experimenter wants to work on this stuff stuff you can add an extension enabling bool on ath_common and perhaps some debugfs knob to enable it.

| | | | | | | | | | | | In an effort to make hw code driver core agnostic read and write operations are defined on the ath_common structure. This patch adds that and makes ath9k use it. This allows drivers like ath9k_htc to define its own read/write ops and still rely on the same hw code. This also paves the way for sharing code between ath9k/ath5k/ath9k_htc. Signed-off-by: Luis R.

* ath9k: Define bus agnostic bluetooth coex prep helperLuis R. Rodriguez2009-10-07
| | | | | | | | | | | | | | | | | | | We disable ASPM when enabling bluetooth coexistance. Disabling ASPM is a bus specific operation. In the future other buses may support bluetooth coexistance, an example is USB. To this end move the current routine which disables ASPM into pci.c, and declare it the PCI bt_coex_prep() helper. Additionally, since ASPM is a PCI-Express primitive ensure we don't ever try to muck with ASPM registers on non PCI-express devices. This also cleans up hw.c to not include bus specific headers or utilities.
