Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next 

John Linville says:

====================
Several drivers see updates: mwifiex, ath9k, iwlwifi, brcmsmac,
wlcore/wl12xx/wl18xx, and a handful of others.  The bcma bus got a
lot of attention from Hauke Mehrtens.  The cfg80211 component gets
a flurry of patches for multi-channel support, and the mac80211
component gets the first few VHT (11ac) and 60GHz (11ad) patches.
This also includes the removal of the iwmc3200 drivers, since the
hardware never became available to normal people.

Additionally, the NFC subsystem gets a series of updates.  According to
Samuel, "Here are the interesting bits:

- A better error management for the HCI stack.
- An LLCP "late" binding implementation for a better NFC SAP usage. SAPs are
  now reserved only when there's a client for it.
- Support for Sony RC-S360 (a.k.a. PaSoRi) pn533 based dongle. We can read and
  write NFC tags and also establish a p2p link with this dongle now.
- A few LLCP fixes."

Finally, this includes another pull of the fixes from the wireless
tree in order to resolve some merge issues.

that was discovered).
Typically, such an event will be propagated to NFC Core from MSGRXWQ context.
Error management
----------------
Errors that occur synchronously with the execution of an NFC Core request are
simply returned as the execution result of the request. These are easy.
Errors that occur asynchronously (e.g. in a background protocol handling thread)
must be reported such that upper layers don't stay ignorant that something
went wrong below and know that expected events will probably never happen.
Handling of these errors is done as follows:
- driver (pn544) fails to deliver an incoming frame: it stores the error such
that any subsequent call to the driver will result in this error. Then it calls
the standard nfc_shdlc_recv_frame() with a NULL argument to report the problem
above. shdlc stores a EREMOTEIO sticky status, which will trigger SMW to
report above in turn.
- SMW is basically a background thread to handle incoming and outgoing shdlc
frames. This thread will also check the shdlc sticky status and report to HCI
when it discovers it is not able to run anymore because of an unrecoverable
error that happened within shdlc or below. If the problem occurs during shdlc
connection, the error is reported through the connect completion.
- HCI: if an internal HCI error happens (frame is lost), or HCI is reported an
error from a lower layer, HCI will either complete the currently executing
command with that error, or notify NFC Core directly if no command is executing.
- NFC Core: when NFC Core is notified of an error from below and polling is
active, it will send a tag discovered event with an empty tag list to the user
space to let it know that the poll operation will never be able to detect a tag.
If polling is not active and the error was sticky, lower levels will return it
at next invocation.

*
*
* This driver implements the bus-specific part of the i2400m for
* SDIO. Check i2400m.h for a generic driver description.
*
* ARCHITECTURE
*
* This driver sits under the bus-generic i2400m driver, providing the
* connection to the device.
*
* When probed, all the function pointers are setup and then the
* bus-generic code called. The generic driver will then use the
* provided pointers for uploading firmware (i2400ms_bus_bm*() in
* sdio-fw.c) and then setting up the device (i2400ms_dev_*() in
* sdio.c).
*
* Once firmware is uploaded, TX functions (sdio-tx.c) are called when
* data is ready for transmission in the TX fifo; then the SDIO IRQ is
* fired and data is available (sdio-rx.c), it is sent to the generic
* driver for processing with i2400m_rx.

*
* THE PROCEDURE
*
* See fw.c for the generic description of this procedure.
*
* This file implements only the SDIO specifics. It boils down to how
* to send a command and waiting for an acknowledgement from the
* device.
*
* All this code is sequential -- all i2400ms_bus_bm_*() functions are
* executed in the same thread, except i2400ms_bm_irq() [on its own by
* the SDIO driver]. This makes it possible to avoid locking.
*
* COMMAND EXECUTION
*
* The generic firmware upload code will call i2400m_bus_bm_cmd_send()
* to send commands.
*
* The SDIO devices expects things in 256 byte blocks, so it will pad
* it, compute the checksum (if needed) and pass it to SDIO.
*
* ACK RECEPTION
*
* This works in IRQ mode -- the fw loader says when to wait for data
* and for that it calls i2400ms_bus_bm_wait_for_ack().
*
* This checks if there is any data available (RX size > 0); if not,
* waits for the IRQ handler to notify about it. Once there is data,
* it is read and passed to the caller. Doing it this way we don't
* need much coordination/locking, and it makes it much more difficult
* for an interrupt to be lost and the wait_for_ack() function getting
* stuck even when data is pending.

help
The Intel Wireless Multicomm 3200 hardware is a combo
card with GPS, Bluetooth, WiMax and 802.11 radios. It
runs over SDIO and is typically found on Moorestown
based platform. This driver takes care of the 802.11
part, which is a fullmac one.
If you choose to build it as a module, it'll be called
iwmc3200wifi.ko.
config IWM_DEBUG
bool "Enable full debugging output in iwmc3200wifi"
depends on IWM && DEBUG_FS
help
This option will enable debug tracing and setting for iwm
You can set the debug level and module through debugfs. By
default all modules are set to the IWL_DL_ERR level.
To see the list of debug modules and levels, see iwm/debug.h
For example, if you want the full MLME debug output:
echo 0xff > /sys/kernel/debug/iwm/phyN/debug/mlme
Or, if you want the full debug, for all modules:
echo 0xff > /sys/kernel/debug/iwm/phyN/debug/level
echo 0xff > /sys/kernel/debug/iwm/phyN/debug/modules
config IWM_TRACING

Say Y here to trace all the commands and responses between
the driver and firmware (including TX/RX frames) with ftrace.
