Subject: [PATCH] brcmfmac: Fix oops when SDIO device is removed.
On removal of SDIO card both functions of card will be getting
a remove call. When the first is hanging in ctrl frame xmit then
the second will cause oops. This patch fixes the xmit ctrl
handling in case of serious errors and also limits the handling
for remove to function 1 only.

Subject: [PATCH] brcmfmac: Simplify watchdog sleep.
The watchdog thread is used to put the SDIO bus to sleep when the
system is idling. This patch simplifies the way it is determined
when sleep can be entered.

Subject: [PATCH] brcmfmac: Fix possible race-condition.
SDIO is using a "shared" variable to handoff ctl frames to DPC
and to see when they are done. In a timeout situation this can
lead to erroneous situation where DPC started to handle the ctl
frame while the timeout expired. This patch will fix this by
adding locking around the shared variable.

Subject: [PATCH] brcmfmac: take save&restore memory into account for SDIO
shared info
The firmware provides pointer to SDIO shared information at end of
RAM during firmware initialization. End of RAM is obviously determined
by the actual ram size, but part of that may be used for save&restore
memory. In that case another location in RAM will hold the pointer.

Subject: [PATCH] brcmfmac: fix watchdog timer regression
The watchdog timer is used to put the device in a low-power mode when
it is idle for some time. This timer is stopped during that mode and
should be restarted upon activity. This has been broken by commit
d4150fced0365 ("brcmfmac: Simplify watchdog sleep."). This patch
restores the behaviour as it was before that commit.

Subject: [PATCH] brcmfmac: avoid runtime-pm for sdio host controller
Several host controllers supporting runtime-pm are causing issues
with our sdio wireless cards because they disable the sdio interrupt
upon going into runtime suspend. This patch avoids that by doing
a pm_runtime_forbid() call during the probe. Tested with Sony Vaio
Duo 13 which uses sdhci-acpi host controller.

Subject: [PATCH] brcmfmac: only support the BCM43455/7 device
Recently support was added for the BCM4345 SDIO chipset by
commit 9c51026509d7 ("brcmfmac: Add support for BCM4345 SDIO chipset")
however this was verified using a BCM43455 device, which is
a more recent revision of the chip. This patch assure that
older revisions are not probed as they would fail.

Subject: [PATCH] brcmfmac: disable MBSS feature for BCM43362
The BCM43362 firmware falsely reports it is capable of providing
MBSS. As a result AP mode no longer works for this device. Therefor
disable MBSS in the driver for this chipset.
