* rsi: disable fw watchdog timer during resetAmitkumar Karwar2018-04-241-0/+1
| | | | | | | | | | Firmware's watchdog timer should be disabled as a part of reset sequence. This change fixes a firmware hang issue observed during stress tests.

* rsi: move descriptor preparation to corePrameela Rani Garnepudi2018-04-241-0/+2
| | | | | | | | | Descriptors preparation is moved to core instead of HAL to avoid synchronization issues in sending TX frames Signed-off-by: Prameela Rani Garnepudi <prameela.j04cs@gmail.com> Signed-off-by: Amitkumar Karwar <amit.karwar@redpinesignals.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rsi: improve RX packet handling in USB interfacePrameela Rani Garnepudi2018-03-131-0/+1
| | | | | | | | | | | | | Curretly, RX packet processing is done sequencially. To improve the efficiency, RX skb queue is introduced. Here, while preparing RX URB skb is allocated and used for RX buffer. When rx done handler is called, enqueue the skb to rx_q and set the thread event. RX thread is modified to dequeue packets from skb queue and process further. Signed-off-by: Prameela Rani Garnepudi <prameela.j04cs@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rsi: add module parameter operating modePrameela Rani Garnepudi2018-03-131-0/+11

* rsi: handle BT traffic in driverSiva Rebbagondla2018-03-131-0/+10
| | | | | | | | | | | | | | | | | BT frames are passed through coex and hal modules to BUS. After firmware is loaded, based on the operating mode CARD READY frame comes for each protocol. When BT card ready is received, BT attach is called. Protocol operations are exchanged between the modules at initialization time. Build flag CONFIG_RSI_COEX is introduced to enable coex support if CONFIG_BT_RSIHCI is enabled. Coex operations are valid if coex mode is greater than 1 only.

* rsi: add beacon changes for AP modePrameela Rani Garnepudi2017-08-171-0/+2
| | | | | | | | | | | 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 tx frame for common device configurationPrameela Rani Garnepudi2017-06-211-0/+3
| | | | | | | | | | | | | | | 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: Add new firmware loading methodPrameela Rani Garnepudi2017-05-241-0/+81
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.
