2015-02-03ath9k: Simplify user pattern configurationSujith Manoharan2-43/+12
There is no need to allocate a new structure and free it for every user pattern, instead use local variables. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-02-03ath9k: Add a debugfs file for WOWSujith Manoharan3-2/+71
This can be used to force WOW for cards that are not present in the supported PCI ID list. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-02-03ath9k: Remove ath9k_hw_wow_event_to_stringSujith Manoharan3-27/+3

2015-02-03ath9k: Remove unused BMISS processingSujith Manoharan3-29/+0
The various variables tracking bmiss interrupts are not really used anywhere except in a debug message. Remove them since they have no functional purpose. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-02-03ath9k: Check WOW triggers properlySujith Manoharan2-30/+28
This patch makes sure that valid WOW triggers are present before trying to suspend the device. Also, introduce and use ATH_OP_WOW_ENABLED to bypass PCI suspend and clear it in resume(). Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-02-03ath9k: Fix wow init/deinitSujith Manoharan3-4/+23
Registering the card as a wakeup source needs to be done once, during initialization. When the WOW configuration changes, the card's status as wakeup source needs to be changed too and this is done via the set_wakeup() callback. Also, make sure the device is removed properly using ath9k_deinit_wow(). Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-02-03ath9k: Check multi-channel context for WOWSujith Manoharan1-0/+9
If CONFIG_ATH9K_CHANNEL_CONTEXT is enabled, check whether multiple contexts are active and if so, return 1 without enabling WOW since we don't support it in this case. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-02-03ath9k: Check early for multi-vif/STA conditionsSujith Manoharan1-15/+7
If multiple interfaces are active or there is no associated station interface, bail out early and return 1 so that mac80211 can proceed with the normal suspend routine. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-02-03ath9k: Remove redundant device_can_wakeup() checkSujith Manoharan1-6/+0
WOW capability is registered with mac80211 only when the device has the ability to wakeup, so there is no need to check in the suspend() routine. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-02-03ath9k: Return early for error conditionsSujith Manoharan1-6/+6
Do not try to cancel work instances and ANI when the device is not present or WOW triggers are not configured. Bail out early and use ath_err() for such error conditions. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-02-03ath9k: Remove ATH9K_HW_WOW_DEVICE_CAPABLESujith Manoharan3-8/+1
Enabling WOW based on the chip is incorrect since it needs to be done for specific sub-devices which have proper platform support. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-01-29ath9k: Enable manual peak detect calibrationSujith Manoharan1-2/+8
On some AR955x/QCA953x boards, noise floor calibration gets stuck and the cause is a hardware/BB issue. To fix this, peak detect calibration in the HW is disabled and is done in the driver instead. There a few differences with the calibration routine for older chips like AR9331. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2015-01-29ath9k: Update AR955x initvalsSujith Manoharan1-2/+2

2015-01-27ath9k and ath9k_htc: rename variable "led_blink"Hong Xu6-8/+8
ath9k and ath9k_htc use the variable name "led_blink" to indicate whether the module parameter "blink" is on. This name is easy to conflict with other variables, and has caused a compiler error found by kbuild test bot. The compiler error is as following: drivers/net/wireless/ath/ath9k/ath9k_htc.o:(.data+0x47c): multiple definition of `led_blink' drivers/net/wireless/ath/ath9k/ath9k.o:(.bss+0x20): first defined here Fixes: 3a939a671225 ("ath9k_htc: Add a module parameter to disable blink") Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Hong Xu <hong@topbug.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2015-01-19ath9k: fix race condition in irq processing during hardware resetFelix Fietkau1-4/+3
To fix invalid hardware accesses, the commit 872b5d814f99 ("ath9k: do not access hardware on IRQs during reset") made the irq handler ignore interrupts emitted after queueing a hardware reset (which disables the IRQ). This left a small time window for the IRQ to get re-enabled by the tasklet, which caused IRQ storms. Instead of returning IRQ_NONE when ATH_OP_HW_RESET is set, disable the IRQ entirely for the duration of the reset.

Use the helper to get rid of the file operations per debugfs file.
