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

John W. Linville says:

====================
I would guess that this is the last big wireless pull request before
the 3.11 merge window...

Regarding the mac80211 bits, Johannes says:

"I have a number of mesh fixes and improvements from Colleen, Jacob,
Ashok and Thomas, powersave fixes in mac80211 from Alex, improved
management-TX from Antonio, and a few various things, including locking
fixes, from others and myself. Overall though, nothing really stands
out."

As for the iwlwifi bits, Johannes says:

"Emmanuel contributed two AP mode fixes, removed an unused field, fixed a
comment and added a warning for something that shouldn't happen in
practice, and I removed the declaration of a function that doesn't even
exist and cleaned up a small include."

"This time I have a number of cleanups, a small fix from Emmanuel and two
performance improvements that combined reduce our driver's CPU
utilisation as much as 75% in high TX-throughput scenarios."

"These two patches fix two issues with using rfkill randomly during
traffic, which would then cause our driver to stop working and not be
able to recover at all."

Regarding the ath6kl bits, Kalle says:

"Here are few simple patches for ath6kl. We have a suspend crash fix for
USB from Shafi, use of mac_pton(), a compiler warning fix and a fix for
module initialisation error path."

Kalle also sends the biggest single item of note, the new ath10k
driver for Qualcomm Atheros 802.11ac CQA98xx devices.

Included is an NFC pull, of which Samuel says:

"These are the pending NFC patches for the 3.11 merge window.

It contains the pending fixes that were on nfc-fixes (nfc-fixes-3.10-2),
along with a few more for the pn544 and pn533 drivers, the LLCP
disconnection path and an LLCP memory leak.

Highlights for this one are:

- An initial secure element API. NFC chipsets can carry an embedded
  secure element or get access to the SIM one. In both cases they
  control the secure elements and this API provides a way to discover,
  enable and disable the available SEs. It also exports that to
  userspace in order for SE focused middleware to actually do something
  with them (e.g. payments).

- NCI over SPI support. SPI is the most complex NCI specified transport
  layer and we now have support for it in the kernel. The next step will
  be to implement drivers for NCI chipsets using this transport like
  e.g. bcm2079x.

- NFC p2p hardware simulation driver. We now have an nfcsim driver that
  is mostly a loopback device between 2 NFC interfaces. It also
  implements the rest of the NFC core API like polling and target
  detection. This driver, with neard running on top of it, allows us to
  completely test the LLCP, SNEP and Handover implementation without
  physical hardware.

- A Firmware update netlink API. Most (All ?) HCI chipsets have a
  special firmware update mode where applications can push a new
  firmware that will be flashed. We now have a netlink API for providing
  that mode to e.g. nfctool."

On top of all that, there are a variety of updates to brcmfmac,
iwlegacy, rtlwifi, wil6210, and the TI wl12xx drivers.  As usual,
the bcma and ssb busses get a little love as well, as do a handful
of others here and there.

+ * Bootloader Messaging Interface (BMI)
+ *
+ * BMI is a very simple messaging interface used during initialization
+ * to read memory, write memory, execute code, and to define an
+ * application entry PC.
+ *
+ * It is used to download an application to QCA988x, to provide
+ * patches to code that is already resident on QCA988x, and generally
+ * to examine and modify state.  The Host has an opportunity to use
+ * BMI only once during bootup.  Once the Host issues a BMI_DONE
+ * command, this opportunity ends.
+ *
+ * The Host writes BMI requests to mailbox0, and reads BMI responses
+ * from mailbox0.   BMI requests all begin with a command
+ * (see below for specific commands), and are followed by
+ * command-specific data.
+ *
+ * Flow control:
+ * The Host can only issue a command once the Target gives it a
+ * "BMI Command Credit", using AR8K Counter #4.  As soon as the
+ * Target has completed a command, it issues another BMI Command
+ * Credit (so the Host can issue the next command).
+ *
+ * BMI handles all required Target-side cache flushing.

+/*
+ * A single CopyEngine (CE) comprises two "rings":
+ *   a source ring
+ *   a destination ring
+ *
+ * Each ring consists of a number of descriptors which specify
+ * an address, length, and meta-data.
+ *
+ * Typically, one side of the PCIe interconnect (Host or Target)
+ * controls one ring and the other side controls the other ring.
+ * The source side chooses when to initiate a transfer and it
+ * chooses what to send (buffer address, length). The destination
+ * side keeps a supply of "anonymous receive buffers" available and
+ * it handles incoming data as it arrives (when the destination
+ * recieves an interrupt).
+ *
+ * The sender may send a simple buffer (address/length) or it may
+ * send a small list of buffers.  When a small list is sent, hardware
+ * "gathers" these and they end up in a single destination buffer
+ * with a single interrupt.
+ *
+ * There are several "contexts" managed by this layer -- more, it
+ * may seem -- than should be needed. These are provided mainly for
+ * maximum flexibility and especially to facilitate a simpler HIF
+ * implementation. There are per-CopyEngine recv, send, and watermark
+ * contexts. These are supplied by the caller when a recv, send,
+ * or watermark handler is established and they are echoed back to
+ * the caller when the respective callbacks are invoked. There is
+ * also a per-transfer context supplied by the caller when a buffer
+ * (or sendlist) is sent and when a buffer is enqueued for recv.
+ * These per-transfer contexts are echoed back to the caller when
+ * the buffer is sent/received.

+ * This API allows the Host to access Target registers directly

+ *
+ * Yet there is some complexity with direct accesses because the
+ * Target's power state is not known a priori. The Host must issue
+ * special PCIe reads/writes in order to explicitly wake the Target
+ * and to verify that it is awake and will remain awake.
+ *
+ * Usage:
+ *
+ *   Use ath10k_pci_read32 and ath10k_pci_write32 to access Target space.
+ *   These calls must be bracketed by ath10k_pci_wake and
+ *   ath10k_pci_sleep.  A single BEGIN/END pair is adequate for
+ *   multiple READ/WRITE operations.
+ *
+ *   Use ath10k_pci_wake to put the Target in a state in
+ *   which it is legal for the Host to directly access it. This
+ *   may involve waking the Target from a low power state, which
+ *   may take up to 2Ms!
+ *
+ *   Use ath10k_pci_sleep to tell the Target that as far as
+ *   this code path is concerned, it no longer needs to remain
+ *   directly accessible.  BEGIN/END is under a reference counter;

+ *		does not get updated based on receive beacon like TSF.  The
+ *		same rules for capturing tsf_timestamp are used to capture
+ *		the wb_timestamp.
+ *
+ * locationing_timestamp
+ *		Timestamp used for locationing.  This timestamp is used to
+ *		indicate fractions of usec.  For example if the MAC clock is
+ *		running at 80 MHz, the timestamp will increment every 12.5
+ *		nsec.  The value starts at 0 and increments to 79 and
+ *		returns to 0 and repeats.  This information is valid for
+ *		every PPDU.  This information can be used in conjunction
+ *		with wb_timestamp to capture large delta times.
+ *
+ * phy_err_code
+ *		See the 1.10.8.1.2 for the list of the PHY error codes.
+ *
+ * phy_err
+ *		Indicates a PHY error was detected for this PPDU.
+ *
+ * rx_location
+ *		Indicates that location information was requested.
+ *
+ * txbf_h_info
+ *		Indicates that the packet data carries H information which
+ *		is used for TxBF debug.
+ *
+ * reserved_18
+ *		Reserved: HW should fill with 0, FW should ignore.
+ *
+ * rx_antenna
+ *		Receive antenna value
+ *
+ * tx_ht_vht_ack
+ *		Indicates that a HT or VHT Ack/BA frame was transmitted in
+ *		response to this receive packet.
+ *
+ * bb_captured_channel
+ *		Indicates that the BB has captured a channel dump.  FW can
+ *		then read the channel dump memory.  This may indicate that
+ *		the channel was captured either based on PCU setting the
+ *		capture_channel bit  BB descriptor or FW setting the
+ *		capture_channel mode bit.
+ *
+ * reserved_19
+ *		Reserved: HW should fill with 0, FW should ignore.
+ *
+ * bb_length
+ *		Indicates the number of bytes of baseband information for
+ *		PPDUs where the BB descriptor preamble type is 0x80 to 0xFF
+ *		which indicates that this is not a normal PPDU but rather
+ *		contains baseband debug information.
+ *
+ * reserved_20
+ *		Reserved: HW should fill with 0, FW should ignore.
+ *
+ * ppdu_done
+ *		PPDU end status is only valid when ppdu_done bit is set.
+ *		Every time HW sets this bit in memory FW/SW must clear this
+ *		bit in memory.  FW will initialize all the ppdu_done dword
+ *		to 0.

+/*
+ * This file specifies the WMI interface for the Unified Software
+ * Architecture.
+ *
+ * It includes definitions of all the commands and events. Commands are
+ * messages from the host to the target. Events and Replies are messages
+ * from the target to the host.
+ *
+ * Ownership of correctness in regards to WMI commands belongs to the host
+ * driver and the target is not required to validate parameters for value,
+ * proper range, or any other checking.
+ *
+ * Guidelines for extending this interface are below.
+ *
+ * 1. Add new WMI commands ONLY within the specified range - 0x9000 - 0x9fff
+ *
+ * 2. Use ONLY u32 type for defining member variables within WMI
+ *    command/event structures. Do not use u8, u16, bool or
+ *    enum types within these structures.
+ *
+ * 3. DO NOT define bit fields within structures. Implement bit fields
+ *    using masks if necessary. Do not use the programming language's bit
+ *    field definition.
+ *
+ * 4. Define macros for encode/decode of u8, u16 fields within
+ *    the u32 variables. Use these macros for set/get of these fields.
+ *    Try to use this to optimize the structure without bloating it with
+ *    u32 variables for every lower sized field.
+ *
+ * 5. Do not use PACK/UNPACK attributes for the structures as each member
+ *    variable is already 4-byte aligned by virtue of being a u32
+ *    type.
+ *
+ * 6. Comment each parameter part of the WMI command/event structure by
+ *    using the 2 stars at the begining of C comment instead of one star to
+ *    enable HTML document generation using Doxygen.
