+* 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>;
+ };
+};
