Kalle Valo says:

====================
Major changes:

wl12xx

* add device tree support for SPI

mwifiex

* add debugfs file to read chip information
* add MSIx support for newer pcie chipsets (8997 onwards)
* add schedule scan support
* add WoWLAN net-detect support
* firmware dump support for w8997 chipset

iwlwifi

* continue the work on multiple Rx queues
* add support for beacon storing used in low power states
* use the regular firmware image of WoWLAN
* fix 8000 devices for Big Endian machines
* more firmware debug hooks
* add support for P2P Client snoozing
* make the beacon filtering for AP mode configurable
* fix transmit queues overflow with LSO

libertas

* add support for setting power save via cfg80211

+* Texas Instruments wl1271 wireless lan controller
+
+The wl1271 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,wl1271"
+- reg :                 Chip select address of device
+- spi-max-frequency :   Maximum SPI clocking speed of device in Hz
+- ref-clock-frequency : Reference clock frequency
+- interrupt-parent, interrupts :
+                        Should contain parameters for 1 interrupt line.
+                        Interrupt parameters: parent, line number, type.
+- vwlan-supply :        Point the node of the regulator that powers/enable the wl1271 chip
+
+Optional properties:
+- clock-xtal :          boolean, clock is generated from XTAL
+
+- Please consult Documentation/devicetree/bindings/spi/spi-bus.txt
+  for optional SPI connection related properties,
+
+Examples:
+
+&spi1 {
+	wl1271@1 {
+		compatible = "ti,wl1271";
+
+		reg = <1>;
+		spi-max-frequency = <48000000>;
+		clock-xtal;
+		ref-clock-frequency = <38400000>;
+		interrupt-parent = <&gpio3>;
+		interrupts = <8 IRQ_TYPE_LEVEL_HIGH>;
+		vwlan-supply = <&vwlan_fixed>;
+	};
+};
