+* Texas Instruments wl12xx/wl18xx wireless lan controller
+
+The wl12xx/wl18xx chips can be connected via SPI or via SDIO. This
+document describes the binding for the SPI connected chip.
+
+Required properties:
+- compatible :          Should be one of the following:
+    * "ti,wl1271"
+    * "ti,wl1273"
+    * "ti,wl1281"
+    * "ti,wl1283"
+    * "ti,wl1801"
+    * "ti,wl1805"
+    * "ti,wl1807"
+    * "ti,wl1831"
+    * "ti,wl1835"
+    * "ti,wl1837"
+- reg :                 Chip select address of device
+- spi-max-frequency :   Maximum SPI clocking speed of device in Hz
+- interrupts :          Should contain parameters for 1 interrupt line.
+- vwlan-supply :        Point the node of the regulator that powers/enable the
+                        wl12xx/wl18xx chip
+
+Optional properties:
+- ref-clock-frequency : Reference clock frequency (should be set for wl12xx)
+- clock-xtal :          boolean, clock is generated from XTAL
+
+- Please consult Documentation/devicetree/bindings/spi/spi-bus.txt
+  for optional SPI connection related properties,
+
+Examples:
+
+For wl12xx family:
+&spi1 {
+	wlcore: wlcore@1 {
+		compatible = "ti,wl1271";
+		reg = <1>;
+		spi-max-frequency = <48000000>;
+		interrupt-parent = <&gpio3>;
+		interrupts = <8 IRQ_TYPE_LEVEL_HIGH>;
+		vwlan-supply = <&vwlan_fixed>;
+		clock-xtal;
+		ref-clock-frequency = <38400000>;
+	};
+};
+
+For wl18xx family:
+&spi0 {
+	wlcore: wlcore@0 {
+		compatible = "ti,wl1835";
+		reg = <0>;
+		spi-max-frequency = <48000000>;
+		interrupt-parent = <&gpio0>;
+		interrupts = <27 IRQ_TYPE_EDGE_RISING>;
+		vwlan-supply = <&vwlan_fixed>;
+	};
+};
