v3:
 * make the bindings device-specific (wl18xx) (Arnd, Mark)

+TI Wilink8 (wl18xx) SDIO devices
+
+This node provides properties for controlling the wilink8 wireless device. The
+node is expected to be specified as a child node to the SDIO controller that
+connects the device to the system.
+
+Required properties:
+ - compatible : Should be "ti,wl18xx".
+ - interrupts : specifies attributes for the out-of-band interrupt.
+
+Optional properties:
+ - interrupt-parent : the phandle for the interrupt controller to which the
+	device interrupts are connected.
+
+Example:
+
+&mmc3 {
+	status = "okay";
+	vmmc-supply = <&wlan_en_reg>;
+	bus-width = <4>;
+	cap-power-off-card;
+	keep-power-in-suspend;
+
+	#address-cells = <1>;
+	#size-cells = <0>;
+	wlcore: wlcore@2 {
+		compatible = "ti,wl18xx";
+		reg = <2>;
+		interrupt-parent = <&gpio0>;
+		interrupts = <19 IRQ_TYPE_NONE>;
+	};
+};
