2013-07-30ath10k: allow deferred regd updateMichal Kazior2-7/+26
Regulatory domain notification hook can be called regardless of the hw state (i.e. before start mac80211 callback). Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2013-07-30ath10k: decouple core start/stop logicMichal Kazior2-12/+34
Enables code reuse for proper hw reconfiguration that is in turn required for proper suspend/hibernation/wowlan support. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2013-07-30ath10k: decouple pci start/stop logicMichal Kazior2-39/+91
Split logic that prepares the device for BMI phase/cleans up related resources. This is necessary for ath10k to be able to restart hw on the fly without reloading the module. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2013-07-30ath10k: improve lockingMichal Kazior1-2/+55
Add more lockdep asserts and a few conf_mutex locks. It's better to be on the safe side. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2013-07-30ath10k: rename hif callbackMichal Kazior3-9/+9
The `set_callbacks` is a more appopriate name for the function. Let's leave `init` for something else. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2013-07-30ath10k: change function to take struct ath10k as argMichal Kazior1-3/+3

2013-07-30ath10k: do not setup rts/frag thresholds for suspended interfacesMichal Kazior1-2/+2
mac80211 calls for rts/frag threshold hooks before any interface is brought back up again when resuming. We would set vdev parameters before given vdev is created lading to a FW crash. rts/frag thresholds will be re-set accordingly in add_interface() hook anyway.

2013-07-30ath10k: setup rts/frag thresholds upon vdev creationMichal Kazior1-1/+19
mac80211 configures rts/frag thresholds per-hw not per-vif. ath10k FW expects those values to be set per-vdev (i.e. per-vif). ath10k should now respect rts/frag thresholds set before a given interface was brought up.

2013-07-30ath10k: fix possible deadlockMichal Kazior1-4/+6
It was possible to have a deadlock due to inverted locking of local->iflist_mtx and ath10k->conf_mutex. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2013-07-30ath10k: fix teardown orderingMichal Kazior1-1/+1

2013-06-27ath10k: leave MMIC generation to the HWMichal Kazior1-1/+0
Apparently HW doesn't require us to generate MMIC for TKIP suite. Each frame was 8 bytes longer than it should be and some APs would drop frames that exceed 1520 bytes of 802.11 payload. This could be observed during throughput tests or fragmented IP traffic. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-06-27ath10k: fix 5ghz channel definitionsMichal Kazior1-24/+24
Nonsense channel flags were being set.

2013-06-12ath10k: mac80211 driver for Qualcomm Atheros 802.11ac CQA98xx devicesKalle Valo30-0/+22092
Here's a new mac80211 driver for Qualcomm Atheros 802.11ac QCA98xx devices. A major difference from ath9k is that there's now a firmware and that's why we had to implement a new driver. The wiki page for the driver is: http://wireless.kernel.org/en/users/Drivers/ath10k The driver has had many authors, they are listed here alphabetically: Bartosz Markowski <bartosz.markowski@tieto.com> Janusz Dziedzic <janusz.dziedzic@tieto.com> Kalle Valo <kvalo@qca.qualcomm.com> Marek Kwaczynski <marek.kwaczynski@tieto.com> Marek Puzyniak <marek.puzyniak@tieto.com> Michal Kazior <michal.kazior@tieto.com> Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
