* rsi: security enhancements for AP modePrameela Rani Garnepudi2017-08-171-0/+1
| | | | | | | | | Station id should be set in load key frame configured to device. For WEP mode, key is configured once from mac80211. This key is saved and configured to device every time a station is connected. Signed-off-by: Prameela Rani Garnepudi <prameela.j04cs@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rsi: add beacon changes for AP modePrameela Rani Garnepudi2017-08-171-5/+8
| | | | | | | | | | | Mac80211 config parameter BEACON_ENABLE is handled. When VAP capabilities frame with AP mode is configured to firmware, beacon events start coming to host at each PreTBTT. At this time, beacon is taken from mac80211, descriptor is prepared and send to firmware.

* rsi: add interface changes for ap modePrameela Rani Garnepudi2017-08-171-0/+3
| | | | | | | | | | AP mode is handled in add_interface callback of mac80211. Also for AP mode, sending rx filter frame to disallow beacons to host is added. Station structures are initialized to NULL.

* rsi: use separate mutex lock for receive threadKarun Eagalapati2017-07-281-0/+2
| | | | | | | | | | | | | Deadlock issue is observed during our stress tests. The root cause for the issue is same lock is used between tx and rx threads.

* rsi: SDIO Rx packet processing enhancementKarun Eagalapati2017-07-281-0/+1
| | | | | | | | | | | | Newer firmware sends information about number of blocks through interrupt only. We don't need to read extra register for this. This patch adds needed driver changes for this enhancment.

* rsi: changes in eeprom read framePrameela Rani Garnepudi2017-07-281-0/+16
| | | | | | | | | | | EEPROM read frame is sent during device initialization to read mac address. The format of the frame is modified in firmware to include eeprom length and offset. This frame does not return firmware version now. Also same frame is sent again to read rf type and band information.

* rsi: use BUILD_BUG_ON check for fsm_stateAmitkumar Karwar2017-07-281-1/+3
| | | | | | | | | | Whenever new fsm_state enum element is added, fsm_state array also needs to be updated. If this change is missed, we may end up doing invalid access in array. BUILD_BUG_ON check will help to avoid this problem. Signed-off-by: Amitkumar Karwar <amit.karwar@redpinesignals.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rsi: add tx frame for common device configurationPrameela Rani Garnepudi2017-06-211-1/+9
| | | | | | | | | | | | | | | After successful loading of firmware, a CARD READY indication is received by host. Common device configuration parameters are sent to the device after this. It includes information like device operating mode (Wi-Fi alone or BT coex), power save related parameters, GPIO information etc. As device supports BT coex, this frame is send in COEX queue initially. Based on the operating mode, CARD READY indication is received from each protocol module in firmware i.e. WLAN, BT.

* rsi: Register interrupt handler before firmware loadPrameela Rani Garnepudi2017-06-211-0/+1
| | | | | | | | | | | | Before firmware load, sometimes false interrupts are received. System hang is observed if interrupt handler is not registered to receive these interrupts. Hence interrupt handler registration is moved before firmware load. We will drop these false interrupts as these are not from the device.

* rsi: use enum for FSM statesAmitkumar Karwar2017-06-211-7/+9
| | | | | | | | | Currently macros are used for FSM states. We will replace it with enum so that new state can be added easily without worrying about macro value. Signed-off-by: Amitkumar Karwar <amit.karwar@redpinesignals.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rsi: Add new firmware loading methodPrameela Rani Garnepudi2017-05-241-0/+10
| | | | | | | | | | | | | | | | | The older firmware loading method has been deprecated and not in use for any chipets. New method is introduced which works based on soft boot loader. In this method, complete RAM image and FLASH image are present in the flash. Before loading the functional firmware, host issues boot loader commands to verify whether firmware to load is different from the current functional firmware. If not, firmware upgrade progresses and boot loader will switch to the new functional firmware. "rs9113_wlan_qspi.rps" is the firmware filename used in this patch.

| | | | | | | | | | | Host interface opearation master_reg_read, master_reg_write and load_data_master_write are added. These functions are needed for the new firmware loading method. As part of this, the function master_access_msword is moved from rsi_91x_sdio_ops.c to rsi_91x_sdio.c.

| | | | | | | | | | Transmit power level in a channel is determined based on the dfs region. To support regulatory rules dfs region should be configured to device during set channel request. Also antenna gain values are taken from the mac80211 channel parameters instead of fixed values.

* cfg80211: remove enum ieee80211_bandJohannes Berg2016-04-121-1/+1
| | | | | | | | | This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
