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

John W. Linville says:

====================
For the mac80211 bits, Johannes says:

"This time, I have a number of small fixes and improvements, and those
are fairly straight-forward. More interesting changes come from Luca
with some preparations for the CSA work, mostly around interface/channel
combinations checking. One other possibly interesting change is a small
one by myself to add NAPI support back to mac80211, which can help
improve TCP behaviour through GRO."

For the Bluetooth bits, Gustavo says:

"This is our first pull request for 3.15, the main feature here is the addition of
the privacy feature for low energy devices. Other than that we have a bunch of small
improvements, fixes, and clean ups all over the tree."

And...

"Another pull request to 3.15. Here we have the second part of the LE private
feature, the LE auto-connect feature and improvements to the power off
procedures. The rest are small improvements, clean up, and fixes."

For the iwlwifi bits, Emmanuel says:

"I have here a whole bunch of various things. Trivial cleanups,
debugfs handlers and new stuff for the new generation of devices
along with new capabilities for monitor mode. We also have support
for power save for dual interface mode, but that is not supported by
the firmware currently available."

And for the Atheros bits, Kalle says:

"For ath10k Alexander did some cleanup to PCI error cases and switched
ath10k to use pci_enable_msi_range(). Michal implemented AP CSA support
and sta_rc_update() operation. I enabled firmware "STA quick kickout"
functionality for faster detection of disappeared clients.

Also there are lots of small fixes to everywhere from various people."

I pulled the wireless tree to avoid some merge conflicts, and I
reverted the staging patch that I had mistakenly merged previously.
Along with that, mwifiex, brcmfmac, wil6210, ath9k, and a few other
drivers get their usual round of updates.  Also notable is the addition
of yet another driver in the rtlwifi family.

 ...

I have amended this commit request to correct the build problems in
staging, including a warning added to one of the staging drivers by
the wireless-next tree.  I also included a fix from Larry Finger to
address an issue found in rtl8723be by Dan Carpenter and smatch.

* Texas Instruments wl1251 wireless lan controller
The wl1251 chip can be connected via SPI or via SDIO. This
document describes the binding for the SPI connected chip.
Required properties:
- compatible : Should be "ti,wl1251"
- reg : Chip select address of device
- spi-max-frequency : Maximum SPI clocking speed of device in Hz
- interrupts : Should contain interrupt line
- interrupt-parent : Should be the phandle for the interrupt controller
that services interrupts for this device
- vio-supply : phandle to regulator providing VIO
- ti,power-gpio : GPIO connected to chip's PMEN pin
Optional properties:
- ti,wl1251-has-eeprom : boolean, the wl1251 has an eeprom connected, which
provides configuration data (calibration, MAC, ...)
- Please consult Documentation/devicetree/bindings/spi/spi-bus.txt
for optional SPI connection related properties,
Examples:
&spi1 {
wl1251@0 {
compatible = "ti,wl1251";
reg = <0>;
spi-max-frequency = <48000000>;
spi-cpol;
spi-cpha;
interrupt-parent = <&gpio2>;
interrupts = <10 IRQ_TYPE_NONE>; /* gpio line 42 */
vio-supply = <&vio>;
ti,power-gpio = <&gpio3 23 GPIO_ACTIVE_HIGH>; /* 87 */
};
};
