2019-01-10rsi: add support for hardware scan offloadPrameela Rani Garnepudi1-0/+1
With the current approach of scanning, roaming delays are observed. Firmware has support for back ground scanning. To get this advantage, mac80211 hardware scan is implemented, which decides type of scan to do based on connected state. When station is in not connected, driver returns with special value 1 to trigger software scan in mac80211. In case of connected state, background scan will be triggered.

2018-07-31rsi: move init_done flag to end of rsi_91x_init().Amol Hanwate1-1/+1
common->init_done flag should set after basic initialization. Hence, moving init_done flag at end of rsi_91x_init(). Signed-off-by: Amol Hanwate <[email protected]> Signed-off-by: Siva Rebbagondla <[email protected]> Signed-off-by: Kalle Valo <[email protected]>

rx_params are getting updated two times in driver, which is not required. Hence, removing duplicate updation of rx_params from rsi_prepare_skb(). Signed-off-by: Amol Hanwate <[email protected]> Signed-off-by: Siva Rebbagondla <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2018-03-13rsi: add module parameter operating modePrameela Rani Garnepudi1-4/+44

2018-03-13rsi: handle BT traffic in driverSiva Rebbagondla1-3/+46
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.

2018-03-13rsi: add coex supportPrameela Rani Garnepudi1-1/+37
With BT support, driver has to handle two streams of data (i.e. wlan and BT). Actual coex implementation is in firmware. Coex module just schedule the packets to firmware by taking them from the corresponding paths. Structures for module and protocol operations are introduced for this purpose. Protocol operations structure is global structure which can be shared among different modules. Move initialization of coex and operating mode values to rsi_91x_init().

2017-10-30rsi: sdio: Add WOWLAN support for S4 hibernate stateKarun Eagalapati1-0/+1
We are disabling of interrupts from firmware in freeze handler. Also setting power management capability KEEP_MMC_POWER to make device wakeup for WoWLAN trigger. At restore, we observed a device reset on some platforms. Hence reloading of firmware and device initialization is performed.
