Arend van Spriel 6e08d757b7 mmc: add SDIO identifiers for Broadcom WLAN devices
The SDIO identifier for Broadcom WLAN devices were defined in the
brcmfmac SDIO driver. Moving the definitions in MMC header file
seems common sense.

Arend van Spriel 9df4d542fc brcmfmac: use custom destructor callback for all netdevice interfaces
The destructor for net devices was set to free_netdev() to get rid
of it and the private data. The private data refers to a brcmf_if
instance, but indirectly it also refers to brcmf_cfg80211_vif which
holds the wdev. This is freed as well by using a new custom destructor
called brcmf_cfg80211_free_netdev().

Arend van Spriel e14799514d brcmfmac: call brcmf_cfg80211_detach() after removal of interfaces
Instead of calling brcmf_cfg80211_detach() in brcmf_del_if() when
deleting the primary interface, call it in brcmf_detach() after
deleting all interfaces.

Arend van Spriel 427dec5fc8 brcmfmac: move wiphy_unregister() call to brcmf_cfg80211_detach()
The wiphy_unregister() call was done in brcmf_free_vif() when the
last interface was being removed. This is not the obvious place to
do that. This patch moves it to the brcmf_cfg80211_detach(). This
removes the need to keep count of interfaces.

Arend van Spriel 43dffbc6be brcmfmac: inform cfg80211 when changing the CONNECTED state
Upon unload of the brcmfmac driver it gave a kernel warning because
cfg80211 still believed to be connected to an AP. The brcmfmac had
already transitioned to disconnected state during unload. This patch
adds informing cfg80211 about this transition. This will get rid of
warning from cfg80211 seen upon module unload:

The condition to disable the clock at the end of brcmf_sdio_bus_init()
was wrong as the bus state is updated by the calling function. Hence,
the clock was always disabled after brcmf_sdio_bus_init() which was
not the intended behaviour.

Johan Hedberg cb6ca8e1ed Bluetooth: Default to no security with L2CAP RAW sockets
L2CAP RAW sockets can be used for things which do not involve
establishing actual connection oriented L2CAP channels. One example of
such usage is the l2ping tool. The default security level for L2CAP
sockets is LOW, which implies that for SSP based connection
authentication is still requested (although with no MITM requirement),
which is not what we want (or need) for things like l2ping. Therefore,
default to one lower level, i.e. BT_SECURITY_SDP, for L2CAP RAW sockets
in order not to trigger unwanted authentication requests.

Marcel Holtmann 81cac64ba2 Bluetooth: Deal with USB devices that are faking CSR vendor
There exists a set of Bluetooth USB devices that show up on the USB
bus as 0a12:0001 and identify themselves as devices from CSR. However
they are not. When sending Read Local Version command they now have
a split personality and say they are from Broadcom.

  < HCI Command: Read Local Version Information (0x04|0x0001) plen 0
  > HCI Event: Command Complete (0x0e) plen 12
      Read Local Version Information (0x04|0x0001) ncmd 1
      status 0x00
      HCI Version: 2.0 (0x3) HCI Revision: 0x3000
      LMP Version: 2.0 (0x3) LMP Subversion: 0x420b
      Manufacturer: Broadcom Corporation (15)

The assumption is that they are neither CSR nor Broadcom based devices
and that they are designed and manufactured by someone else.

For the most parts they follow the Bluetooth HCI specification and
can be used as standard Bluetooth devices. However they have the
minor problem that the Delete Stored Link Key command is not working
as it should.

During the Bluetooth controller setup, this command is needed if
stored link keys are supported. For these devices it has to be
assumed that this is broken and so just set a quirk to clearly
indicate the behavior. After that the setup can just proceed.

Now the trick part is to detect these faulty devices since we do
not want to punish all CSR and all Broadcom devices. The original
devices do actually work according to the specification.

What is known so far is that these broken devices set the USB bcdDevice
revision information to 1.0 or less.

T:  Bus=02 Lev=01 Prnt=01 Port=08 Cnt=03 Dev#=  9 Spd=12   MxCh= 0
D:  Ver= 2.00 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs=  1
P:  Vendor=0a12 ProdID=0001 Rev= 1.00
S:  Manufacturer=Bluetooth v2.0
S:  Product=Bluetooth V2.0 Dongle

T:  Bus=05 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=12   MxCh= 0
D:  Ver= 1.10 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs=  1
P:  Vendor=0a12 ProdID=0001 Rev= 0.07

In case of CSR devices, the bcdDevice revision contains the firmware
build ID and that is normally a higher value. If the bcdDevice revision
is 1.0 or less, then an extra setup stage is checking if Read Local
Version returns CSR manufacturer information. If not then it will be
assumed that this is a broken device and the Delete Stored Link Key
command will be marked as broken.

Not correctly supporting this command causes the controller setup to
fail and will make a device not work. However sending the command for
controller that handle stored link keys is important. This quirk
allows a driver to disable the command if it knows that this command
handling is broken.

Thierry Escande 4f319e3251 NFC: digital: Use NFC_NFCID3_MAXSIZE from nfc.h
This removes the declaration of NFCID3 size in digital_dep.c and now
uses the one from nfc.h.

This also removes a faulty and unneeded call to max().

Some ACR122 firmwares seem to send 0 length data frames. Before using
that length as a data index, we check that it's not 0. If it is we
report the frame as being invalid.

Samuel Ortiz a434c24074 NFC: Only warn on SE discovery error
SE discovery errors are currently overwriting the dev_up() return error.
This is wrong for many reasons:

- We don't want to report an error if we actually brought the device up
  but it failed to discover SEs. By doing so we pretend we don't have an
  NFC functional device even we do. The only thing we could not do was
  checking for SEs availability. This is the false negative case.

- In some cases the actual device power up failed but the SE discovery
  succeeded. Userspace then believes the device is up while it's not.
  This is the false positive case.

Some of the EEPROM configurations that are assigned by the PN544 driver
are set by the firmware and should not be modified by the driver. Others
are certain user mode configurations that are currently getting set to values

most user and system mode configurations to the firmware defaults.
