Re-apply Dong Aisheng's patch for MLK-13190, as the issue
reappeared with bcmdhd update v1.141.100.6:BCMDHD_SDIO needs to be tristate for the correct dependency
of MMC core subsystem.
And the old driver buildin mode is static defined by DRIVER_TYPE.
Fix it to depend on CONFIG_BCMDHD_SDIO.Signed-off-by: Dong Aisheng

Enable OOB feature for MX6Q/DL SDB, MX6SL EVK, MX6SX SDB, MX7D SDB boards.
NOTE: The performance optimization option CONFIG_BCM4339 is disabled
by default due to a WiFi driver issue that it breaks MX6SL EVK.If user want to test performance on the above platforms (except MX6SL EVK),
CONFIG_BCM4339 has to be enabled manually.Signed-off-by: Dong Aisheng

The patch is delivered by Cypress to add OOB switch interface
and a P2P stability fix.Whether to enable OOB is controlled by the gpios property under
bcmdhd_wlan_0 node.
e.g.
bcmdhd_wlan_0: bcmdhd_wlan@0 {
compatible = "android,bcmdhd_wlan";
gpios = ; /* WL_HOST_WAKE */
wlreg_on-supply = ;
};If valid gpios property found, then driver will consider to use
OOB feature.Signed-off-by: Dong Aisheng

Bcmdhd wifi driver default build as module, now default build in
this wifi driver. To support this build in feature, this patch
add flag ENABLE_INSMOD_NO_FW_LOAD, and use extern function
sdio_reset_comm() as instead.Signed-off-by: Haibo Chen

Some major fixes delivered by Broadcom.
1. Initialize nd_config parameter of cfg80211_wowlan to NULL
2. Avoid using hardcoded dummy channel number while creating p2p interface
3. Avoid creation of multiple instance of wl_event_handler thread.Signed-off-by: Dong Aisheng

bcmdhd can't support removing host during suspend and
driver crash when detect card after resume due to no response
to CMD7.
It looks bcmdhd has a special requirement to enumerate card
by itself which is incompatible with current MMC core.
So implement post-cd feature to allow driver to detect card
as it wants, then we add back non-removable capability
to avoid MMC core to redetect card after resume.root@imx6qdlsolo:~# echo standby > /sys/power/state

Current driver will meet the following warning on MX6SL platform which does
not support ADMA.
It is caused by the driver is using fixed scatter gather DMA not matter whether
the host supports or not. Then the host without ADMA capability will warning
if found the DMA sg_count is non-1.
Change the driver a bit to avoid multi DMA scatter list if found the
host->max_segs is only 1 to fix the issue.root@imx6slevk:~# udhcpc -i wlan0

As part of starting up IBSS, CFG80211 driver needs BSS information to be
plumbed into it. Hence in DHD we call cfg80211_infrom_bss() and it needs whole
frame consist of IEs contained in beacon frame. But FW was passing frame buffer
with some extra bytes preceded and when same is plumbed into CFG80211 it was not
able to decode the frame and it ignores the frame as result we get such warnings.
Using latest FW delivered by Broadcom to fix the issue.As well as wl_cfg80211.c changes are essential. This change is actually fix certain
warnings seen when moving between IBSS and BSS network mode.
Changes must be done in wl_cfg80211_change_virtual_iface() which you can find at
wl_cfg80211.c and this file is not specific wl tool.Signed-off-by: Dong Aisheng

code will crash trying to access the queue_info array at the

commit d1f1c0e289e1bc46cd6873ba6dd6c627f459e7fa upstream.
Starting with commit d94a461d7a7d ("ath9k: use ieee80211_tx_status_noskb
where possible") the driver uses rcu_read_lock() && rcu_read_unlock(), yet on
returning early in ath_tx_edma_tasklet() the unlock is missing leading to stalls
and suspicious RCU usage:===============================

commit 79e57dd113d307a6c74773b8aaecf5442068988a upstream.
The active_high LED of my Wistron DNMA-92 is still being recognized as
active_low on 4.7.6 mainline. When I was preparing my former commit
0f9edcdd88a9 ("ath9k: Fix LED polarity for some Mini PCI AR9220 MB92
cards.") to fix that I must have somehow messed up with testing, because
I tested the final version of that patch before sending it, and it was
apparently working; but now it is not working on 4.7.6 mainline.I initially added the PCI_DEVICE_SUB section for 0x0029/0x2096 above the
PCI_VDEVICE section for 0x0029; but then I moved the former below the
latter after seeing how 0x002A sections were sorted in the file.This turned out to be wrong: if a generic PCI_VDEVICE entry (that has
both subvendor and subdevice IDs set to PCI_ANY_ID) is put before a more
specific one (PCI_DEVICE_SUB), then the generic PCI_VDEVICE entry will
match first and will be used.With this patch, 0x0029/0x2096 has finally got active_high LED on 4.7.6.
While I'm at it, let's fix 0x002A too by also moving its generic definition
below its specific ones.Fixes: 0f9edcdd88a9 ("ath9k: Fix LED polarity for some Mini PCI AR9220 MB92 cards.")

commit 91851cc7a939039bd401adb6ca3da4402bec1d0c upstream.
Commit b2d70d4944c1 ("ath9k: make GPIO API to support both of WMAC and
SOC") refactored ath9k_hw_gpio_get() to support both WMAC and SOC GPIOs,
changing the return on success from 1 to BIT(gpio). This broke some callers
like ath_is_rfkill_set(). This doesn't fix any known bug in mainline at the
moment, but should be fixed anyway.Instead of fixing all callers, change ath9k_hw_gpio_get() back to only
return 0 or 1.Fixes: b2d70d4944c1 ("ath9k: make GPIO API to support both of WMAC and SOC")
