+VIA/Wondermedia VT8500 GPIO Controller
+-----------------------------------------------------
+
+Required properties:
+- compatible : "via,vt8500-gpio", "wm,wm8505-gpio"
+        or "wm,wm8650-gpio" depending on your SoC
+- reg : Should contain 1 register range (address and length)
+- #gpio-cells : should be <3>.
+        1) bank
+        2) pin number
+        3) flags - should be 0
+
+Example:
+
+        gpio: gpio-controller@d8110000 {
+                compatible = "via,vt8500-gpio";
+                gpio-controller;
+                reg = <0xd8110000 0x10000>;
+                #gpio-cells = <3>;
+        };
+
+        vibrate {
+                gpios = <&gpio 0 1 0>; /* Bank 0, Pin 1, No flags */
+        };
