Remove extend 5 ms related operation at WLAN media status notify. The mechanism should be enable only while DUT connect to a AP that it doesn't follow our power save control or its rate is decreasing unusually sensitive. So we extend a extra slot to save the transmission rate. The original logic will always extend WLAN slot. It will lead to BT slot always decrease 5 ms. Remove write scoreboard action at WLAN media status notify. It has already done in WLAN info notify. Signed-off-by:

Force set the coexistence to BT high priority during WLAN initial/power-on step. Since the duration the related setting may be not ready yet. The score board is not related to scan when initialing, remove the scan parameter. Signed-off-by:

While the mechanism goes to 2G_free_run or WL5G_BT2G, set BT to hardware PTA mode to get a more efficiently performance. Add a flag to indicate antenna switch is supported or not so that the IC serials which has different antenna structure can set antenna correctly. Signed-off-by:

Life time related setting is related to WLAN active port number, not its mode. The original setting may cause poor WLAN performance. In most case, WLAN TX limitation is helpful for BT in coexistence scenario, especially for A2DP quality. So this is necessary to fix the setting and constraint it. Signed-off-by:

Add counter to count BT info C2H command for debug usage. It could present the C2H channel situation. Fix BT IQK state decision condition for counting. The original condition is wrong, it would cause coexistence mechanism going to the wrong strategy. New format supports getting TDMA parameter from WL firmware, since coexistence needs current TDMA parameter to decide strategy. Remove unnecessary operations about scoreboard, it is not a must for current version. Signed-off-by:

Some register definition and bit definition were incorrect. e.g. REG_BT_COEX_V2 should be word alignment to meet the coding style. e.g. set REG_BT_TDMA_TIME[5:0]=0x5, But the original is to set REG_BT_TDMA_TIME[7:0]=0x5. This will cause unexpected hardware behavior. Signed-off-by:

The interrupt handling of the RS911x is particularly heavy. For each RX packet, the card does three SDIO transactions, one to read interrupt status register, one to RX buffer length, one to read the RX packet(s). This translates to ~330 uS per one cycle of interrupt handler. In case there is more incoming traffic, this will be more. The drivers/mmc/core/sdio_irq.c has the following comment, quote "Just like traditional hard IRQ handlers, we expect SDIO IRQ handlers to be quick and to the point, so that the holding of the host lock does not cover too much work that doesn't require that lock to be held." The RS911x interrupt handler does not fit that. This patch therefore changes it such that the entire IRQ handler is moved to the RX thread instead, and the interrupt handler only wakes the RX thread. This is OK, because the interrupt handler only does things which can also be done in the RX thread, that is, it checks for firmware loading error(s), it checks buffer status, it checks whether a packet arrived and if so, reads out the packet and passes it to network stack. Moreover, this change permits removal of a code which allocated an skbuff only to get 4-byte-aligned buffer, read up to 8kiB of data into the skbuff, queue this skbuff into local private queue, then in RX thread, this buffer is dequeued, the data in the skbuff as passed to the RSI driver core, and the skbuff is deallocated. All this is replaced by directly calling the RSI driver core with local buffer. Signed-off-by:

The problem is now that _mwifiex_fw_dpc() calls mwifiex_free_adapter() in case firmware initialization fails. That ends up calling mwifiex_cleanup_pcie(). Note that all those calls are still running on the workqueue. So when mwifiex_cleanup_pcie() now calls cancel_work_sync(), it's really waiting on itself to complete, causing a deadlock. This commit fixes the deadlock by skipping cancel_work_sync() on a reset failure path.
