pull request: wireless-next 2014-12-08

Please pull this last batch of pending wireless updates for the 3.19 tree...

For the wireless bits, Johannes says:

"This time I have Felix's no-status rate control work, which will allow
drivers to work better with rate control even if they don't have perfect
status reporting. In addition to this, a small hwsim fix from Patrik,
one of the regulatory patches from Arik, and a number of cleanups and
fixes I did myself.

Of note is a patch where I disable CFG80211_WEXT so that compatibility
is no longer selectable - this is intended as a wake-up call for anyone
who's still using it, and is still easily worked around (it's a one-line
patch) before we fully remove the code as well in the future."

For the Bluetooth bits, Johan says:

"Here's one more bluetooth-next pull request for 3.19:

 - Minor cleanups for ieee802154 & mac802154
 - Fix for the kernel warning with !TASK_RUNNING reported by Kirill A.
   Shutemov
 - Support for another ath3k device
 - Fix for tracking link key based security level
 - Device tree bindings for btmrvl + a state update fix
 - Fix for wrong ACL flags on LE links"

And...

"In addition to the previous one this contains two more cleanups to
mac802154 as well as support for some new HCI features from the
Bluetooth 4.2 specification.

From the original request:

'Here's what should be the last bluetooth-next pull request for 3.19.
It's rather large but the majority of it is the Low Energy Secure
Connections feature that's part of the Bluetooth 4.2 specification. The
specification went public only this week so we couldn't publish the
corresponding code before that. The code itself can nevertheless be
considered fairly mature as it's been in development for over 6 months
and gone through several interoperability test events.

Besides LE SC the pull request contains an important fix for command
complete events for mgmt sockets which also fixes some leaks of hci_conn
objects when powering off or unplugging Bluetooth adapters.

A smaller feature that's part of the pull request is service discovery
support. This is like normal device discovery except that devices not
matching specific UUIDs or strong enough RSSI are filtered out.

Other changes that the pull request contains are firmware dump support
to the btmrvl driver, firmware download support for Broadcom BCM20702A0
variants, as well as some coding style cleanups in 6lowpan &
ieee802154/mac802154 code.'"

For the NFC bits, Samuel says:

"With this one we get:

- NFC digital improvements for DEP support: Chaining, NACK and ATN
  support added.

- NCI improvements: Support for p2p target, SE IO operand addition,
  SE operands extensions to support proprietary implementations, and
  a few fixes.

- NFC HCI improvements: OPEN_PIPE and NOTIFY_ALL_CLEARED support,
  and SE IO operand addition.

- A bunch of minor improvements and fixes for STMicro st21nfcb and
  st21nfca"

For the iwlwifi bits, Emmanuel says:

"Major works are CSA and TDLS. On top of that I have a new
firmware API for scan and a few rate control improvements.
Johannes find a few tricks to improve our CPU utilization
and adds support for a new spin of 7265 called 7265D.
Along with this a few random things that don't stand out."

And...

"I deprecate here -8.ucode since -9 has been published long ago.
Along with that I have a new activity, we have now better
a infrastructure for firmware debugging. This will allow to
have configurable probes insides the firmware.
Luca continues his work on NetDetect, this feature is now
complete. All the rest is minor fixes here and there."

For the Atheros bits, Kalle says:

"Only ath10k changes this time and no major changes. Most visible are:

o new debugfs interface for runtime firmware debugging (Yanbo)

o fix shared WEP (Sujith)

o don't rebuild whenever kernel version changes (Johannes)

o lots of refactoring to make it easier to add new hw support (Michal)

There's also smaller fixes and improvements with no point of listing
here."

In addition, there are a few last minute updates to ath5k,
ath9k, brcmfmac, brcmsmac, mwifiex, rt2x00, rtlwifi, and wil6210.
Also included is a pull of the wireless tree to pick-up the fixes
originally included in "pull request: wireless 2014-12-03"...

Please let me know if there are problems!

btmrvl
------
Required properties:
- compatible : must be "btmrvl,cfgdata"
Optional properties:
- btmrvl,cal-data : Calibration data downloaded to the device during
initialization. This is an array of 28 values(u8).
- btmrvl,gpio-gap : gpio and gap (in msecs) combination to be
configured.
Example:
GPIO pin 13 is configured as a wakeup source and GAP is set to 100 msecs
in below example.
btmrvl {
compatible = "btmrvl,cfgdata";
btmrvl,cal-data = /bits/ 8 <
0x37 0x01 0x1c 0x00 0xff 0xff 0xff 0xff 0x01 0x7f 0x04 0x02
0x00 0x00 0xba 0xce 0xc0 0xc6 0x2d 0x00 0x00 0x00 0x00 0x00
0x00 0x00 0xf0 0x00>;
btmrvl,gpio-gap = <0x0d64>;
