		Gateworks PLD GPIO controller bindings

		The GPIO controller should be a child node on an I2C bus,
		see: i2c/i2c.txt for details.

		Required properties:
		- compatible: Should be "gateworks,pld-gpio"
		- reg: I2C slave address
		- gpio-controller: Marks the device node as a GPIO controller.
		- #gpio-cells: Should be <2>. The first cell is the gpio number and
		the second cell is used to specify optional parameters.

		Example:

		pld@56 {
		compatible = "gateworks,pld-gpio";
		reg = <0x56>;
		gpio-controller;
		#gpio-cells = <2>;
		};
