+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 */
+ };
