2011-11-11ath6kl: fix WLAN_ENABLE usage in ath6kl_close()Kalle Valo1-1/+2
If ath6kl_init_hw_stop() failed with an error WLAN_ENABLED would not be cleared. Found during code review and just a theoretical issue. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: power down hardware when interface is downKalle Valo6-7/+64
The benefit from this is that user space can control hardware's power state by putting interface up and down. This is handy if firmware gets to some weird state. The downside will be that putting interface up takes a bit longer, I was measuring ~500 ms during interface up. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: create ath6kl_hif_stop()Kalle Valo3-0/+53
This is to reset hif layer for powering down hw. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: change name of sdio driver to ath6klKalle Valo1-1/+1
Currently the name of the driver in struct sdio_driver is "ath6kl_sdio", this is for example what uevent advertises. This is wrong as the module is named as ath6kl.ko. Change it to "ath6kl" so that the names match. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: don't print an error for canceled packetsKalle Valo1-2/+3
ath6kl_tx_complete() was printing an error when packet was canceled. That causes unnecessary errors when hardware is powered off. Also change the error to a warning and cleanup the message. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: create ath6kl_htc_reset()Kalle Valo1-42/+49
When rebooting hardware we need to reset the htc state in ath6kl_htc_stop(). Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: add a timeout to ath6kl_hif_intr_bh_handler()Kalle Valo2-1/+5
It's possible to busyloop forever in ath6kl_hif_intr_bh_handler(). Add a check that it lasts only one second. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: remove useless cleanup call from ath6kl_bmi_done()Kalle Valo1-2/+0
aht6kl core code will call the cleanup function when the device is removed. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: separate hardware boot code from module initialisation codeKalle Valo1-77/+106
Refactor the code needed to boot the hardware to a separate function so that it will be easier boot and shutdown hardware. No functional changes (hopefully). Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: merge ath6kl_init() to ath6kl_core_init()Kalle Valo1-83/+65
In preparation for splitting module initialisation and hardware boot code from each other. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: add a fixme to ath6kl_htc_wait_target()Kalle Valo1-0/+4
This doesn't look right, but investigate it later. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: move power control from sdio to coreKalle Valo4-16/+37
In preparation for cutting down power from the chip on the fly. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: rename ath6kl_wmi_qos_state_init() to _wmi_reset()Kalle Valo2-5/+3
Just to make it more clear that this function is supposed to reset wmi related variables. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: don't use cfg80211_scan_request after cfg80211_scan_done()Kalle Valo1-2/+4
Use of cfg80211_scan_request is not valid after calling cfg80211_scan_done() but ath6kl_cfg80211_scan_complete_event() was doing exactly that. Change the function to call cfg80211_scan_done() last. This was found during code review, I didn't see any visible problems due to this bug. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: fix missing copy of action frame contentsAarthi Thiruvengadam1-0/+1
The wpa_supplicant was receiving incorrect frame contents in the callback function that indicates the status of the frame transmitted. This patch fixes a missing copy of the frame contents to a local buffer. The local buffer keeps track of the last sent management frame.

2011-11-11ath6kl: Report unique remain-on-channel cookie valuesJouni Malinen3-4/+22
Even though only a single concurrent remain-on-channel operation is supported, there may be two pending remain-on-channel events (one to indicate end of a canceled operation and another to indicate start of a new operation). User space won't be able to distinguish these events unless unique cookies are used. The previous behavior resulted in wpa_supplicant getting quite confused about the driver's offchannel state in various sequences and this made the P2P state machine behave incorrectly. Use of more than a single remain-on-channel cookie value fixes this. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: Fix compilation error from of.hSangwook Lee1-0/+1
When compiling ath6kl for ARM with device tree tree compilation fails with errors like: include/linux/of.h: In function 'of_property_read_u32_array': include/linux/of.h:249:10: error: 'ENOSYS' undeclared Workaround this by including errno.h from init.c. kvalo: improved commit log Signed-off-by: Sangwook Lee <sangwook.lee@linaro.org> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: Implement support for power parameter control from userspaceRishi Panjwani1-0/+63
In order to allow user space based control of power parameters, we use available debugfs infrastructure. With these features user can control power consumption by adjusting various sleep/wake up related parameters. The feature has been added for testing purposes. All 5 parameters are mandatory in correct order. They have to be written to the power_params file. These are: 1) idle_period 2) no_of_pspoll 3) dtim_policy 4) tx_wakeup_policy 5) no_tx_to_wakeup Example: echo "200 1 0 1 1" > power_params Signed-off-by: Rishi Panjwani <rpanjwan@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: Implement support for listen interval from userspaceRishi Panjwani1-0/+64
In order to allow user space based control of listen interval, we use available debugfs infrastructure. Listen interval implies how frequently we want the WLAN chip to wake up and synchronize the beacons in case it is in sleep mode. The command requires two parameters in the following order: 1) listen_interval_time 2) listen_interval_beacons The user has to write the listen interval_time (in msecs) and listen_interval_beacons (in no. of beacons) to the listen_interval file in ath6kl debug directory. Example: echo "30 1" > listen_interval Signed-off-by: Rishi Panjwani <rpanjwan@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: add support for WPSAarthi Thiruvengadam2-0/+19

2011-11-11ath6kl: move all credit distribution code to htc.cKalle Valo5-302/+295
As htc is the only user there's no reason to keep it in main.c. No functional changes. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-11-11ath6kl: rename struct htc_credit_state_info to ath6kl_htc_credit_infoKalle Valo6-38/+45
