+TPIC2810 GPIO controller bindings
+
+Required properties:
+ - compatible          : Should be "ti,tpic2810".
+ - reg                 : The I2C address of the device
+ - gpio-controller     : Marks the device node as a GPIO controller.
+ - #gpio-cells         : Should be two. For consumer use see gpio.txt.
+
+Example:
+
+       gpio@60 {
+               compatible = "ti,tpic2810";
+               reg = <0x60>;
+               gpio-controller;
+               #gpio-cells = <2>;
+       };
