Alistair Francis 1061813243 Revert "brcmfmac: Loading the correct firmware for brcm43456"
This reverts commit e3062e05e1.

There is no brcmfmac43456-sdio.* firmware in the linux-firmware repo,
and the brcmfmac43455-sdio.* works fine, so let's just use that.

Leon Romanovsky 6417f03132 module: remove never implemented MODULE_SUPPORTED_DEVICE
MODULE_SUPPORTED_DEVICE was added in pre-git era and never was
implemented. We can safely remove it, because the kernel has grown
to have many more reliable mechanisms to determine if device is
supported or not.

Colin Ian King 4773acf3d4 b43: N-PHY: Fix the update of coef for the PHY revision >= 3case
The documentation for the PHY update [1] states:

Loop 4 times with index i

    If PHY Revision >= 3
        Copy table[i] to coef[i]
    Otherwise
        Set coef[i] to 0

the copy of the table to coef is currently implemented the wrong way
around, table is being updated from uninitialized values in coeff.
Fix this by swapping the assignment around.

Hans de Goede a338c874d3 brcmfmac: Add DMI nvram filename quirk for Voyo winpad A15 tablet
The Voyo winpad A15 tablet contains quite generic names in the sys_vendor
and product_name DMI strings, without this patch brcmfmac will try to load:
rcmfmac4330-sdio.To be filled by O.E.M.-To be filled by O.E.M..txt
as nvram file which is a bit too generic.

Add a DMI quirk so that a unique and clearly identifiable nvram file name
is used on the Voyo winpad A15 tablet.

While preparing a matching linux-firmware update I noticed that the nvram
is identical to the nvram used on the Prowise-PT301 tablet, so the new DMI
quirk entry simply points to the already existing Prowise-PT301 nvram file.

Johannes Berg a05829a722 cfg80211: avoid holding the RTNL when calling the driver
Currently, _everything_ in cfg80211 holds the RTNL, and if you
have a slow USB device (or a few) you can get some bad lock
contention on that.

Fix that by re-adding a mutex to each wiphy/rdev as we had at
some point, so we have locking for the wireless_dev lists and
all the other things in there, and also so that drivers still
don't have to worry too much about it (they still won't get
parallel calls for a single device).

Then, we can restrict the RTNL to a few cases where we add or
remove interfaces and really need the added protection. Some
of the global list management still also uses the RTNL, since
we need to have it anyway for netdev management, but we only
hold the RTNL for very short periods of time here.

Johannes Berg 2fe8ef1062 cfg80211: change netdev registration/unregistration semantics
We used to not require anything in terms of registering netdevs
with cfg80211, using a netdev notifier instead. However, in the
next patch reducing RTNL locking, this causes big problems, and
the simplest way is to just require drivers to do things better.

Change the registration/unregistration semantics to require the
drivers to call cfg80211_(un)register_netdevice() when this is
happening due to a cfg80211 request, i.e. add_virtual_intf() or
del_virtual_intf() (or if it somehow has to happen in any other
cfg80211 callback).

Otherwise, in other contexts, drivers may continue to use the
normal netdev (un)registration functions as usual.

Internally, we still use the netdev notifier and track (by the
new wdev->registered bool) if the wdev had already been added
to cfg80211 or not.

Luca Pesce e862a3e408 brcmfmac: clear EAP/association status bits on linkdown events
This ensure that previous association attempts do not leave stale statuses
on subsequent attempts.

This fixes the WARN_ON(!cr->bss)) from __cfg80211_connect_result() when
connecting to an AP after a previous connection failure (e.g. where EAP fails
due to incorrect psk but association succeeded). In some scenarios, indeed,
brcmf_is_linkup() was reporting a link up event too early due to stale
BRCMF_VIF_STATUS_ASSOC_SUCCESS bit, thus reporting to cfg80211 a connection
result with a zeroed bssid (vif->profile.bssid is still empty), causing the
WARN_ON due to the call to cfg80211_get_bss() with the empty bssid.

Brcmfmac got warning message when hitting FW crash in TX throughput test
with fcmode=2. It's caused by FMAC flushed TXQ in brcmf_sdio_bus_stop
but without doing hanger slot cleanup. Therefore, we move
brcmf_remove_interface before brcmf_bus_stop to make sure the hanger
slot is clean when flushing TXQ.

Sebastian Andrzej Siewior c597ede403 net: brcmfmac: Convey allocation mode as argument
The usage of in_interrupt() in drivers is phased out and Linus clearly
requested that code which changes behaviour depending on context should
either be seperated or the context be conveyed in an argument passed by the
caller, which usually knows the context.

brcmf_fweh_process_event() uses in_interrupt() to select the allocation
mode GFP_KERNEL/GFP_ATOMIC. Aside of the above reasons this check is
incomplete as it cannot detect contexts which just have preemption or
interrupts disabled.

All callchains leading to brcmf_fweh_process_event() can clearly identify
the calling context. Convey a 'gfp' argument through the callchains and let
the callers hand in the appropriate GFP mode.

This has also the advantage that any change of execution context or
preemption/interrupt state in these callchains will be detected by the
memory allocator for all GFP_KERNEL allocations.

Sebastian Andrzej Siewior d067c0fa29 net: brcmfmac: Replace in_interrupt()
brcmf_sdio_isr() is using in_interrupt() to distinguish if it is called
from a interrupt service routine or from a worker thread.

Passing such information from the calling context is preferred and
requested by Linus, so add an argument `in_isr' to brcmf_sdio_isr() and let
the callers pass the information about the calling context.

Two minor conflicts:

1) net/ipv4/route.c, adding a new local variable while
   moving another local variable and removing it's
   initial assignment.

2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes.
   One pretty prints the port mode differently, whilst another
   changes the driver to try and obtain the port mode from
   the port node rather than the switch node.

When wlc_phy_txpwr_srom_read_lcnphy fails in wlc_phy_attach_lcnphy,
the allocated pi->u.pi_lcnphy is leaked, since struct brcms_phy will be

Dmitry Osipenko cc95fa8152 brcmfmac: set F2 SDIO block size to 128 bytes for BCM4329
Setting F2 block size to 128 bytes for BCM4329 allows to significantly
improve RX throughput on NVIDIA Tegra20. Before this change the throughput
was capped to 30 Mbit/s on Tegra, now throughput is at 40 Mbit/s, which is
a maximum throughput for the BCM4329 chip. The F2 block size is borrowed
from the downstream BCMDHD driver. The comment in the BCMDHD driver says
that 128B improves throughput and turns out that it works for the brcmfmac
as well.

Dmitry Osipenko 1a867a6230 brcmfmac: drop chip id from debug messages
The chip ID was already printed out at the time when debug message about
the changed F2 watermark is printed, hence let's drop the unnecessary part
of the debug messages. This cleans code a tad and also allows to re-use
the F2 watermark debug messages by multiple chips.

Dmitry Osipenko 317da69d10 brcmfmac: increase F2 watermark for BCM4329
This patch fixes SDHCI CRC errors during of RX throughput testing on
BCM4329 chip if SDIO BUS is clocked above 25MHz. In particular the
checksum problem is observed on NVIDIA Tegra20 SoCs. The good watermark
value is borrowed from downstream BCMDHD driver and it's matching to the
value that is already used for the BCM4339 chip, hence let's re-use it
for BCM4329.
