+* TPS65086 GPO Controller bindings
+
+Required properties:
+ - compatible          : Should be "ti,tps65086-gpio".
+ - gpio-controller     : Marks the device node as a GPIO Controller.
+ - #gpio-cells         : Should be two. The first cell is the pin number
+                           and the second cell is used to specify flags.
+                           See ../gpio/gpio.txt for possible values.
+
+Example:
+
+       gpio4: gpio {
+               compatible = "ti,tps65086-gpio";
+               gpio-controller;
+               #gpio-cells = <2>;
+       };
