+TI Wilink 6/7/8 (wl12xx/wl18xx) SDIO devices
+
+This node provides properties for controlling the wilink 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 one of the following:
+ * "ti,wl1271"
+ * "ti,wl1273"
+ * "ti,wl1281"
+ * "ti,wl1283"
+ * "ti,wl1801"
+ * "ti,wl1805"
+ * "ti,wl1807"
+ * "ti,wl1831"
+ * "ti,wl1835"
+ * "ti,wl1837"
+ - 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.
+ - ref-clock-frequency : ref clock frequency in Hz
+ - tcxo-clock-frequency : tcxo clock frequency in Hz
+
+Note: the *-clock-frequency properties assume internal clocks. In case of external
+clock, new bindings (for parsing the clock nodes) have to be added.
+
+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,wl1835";
+ reg = <2>;
+ interrupt-parent = <&gpio0>;
+ interrupts = <19 IRQ_TYPE_LEVEL_HIGH>;
+ };
+};
