1Gateworks PLD GPIO controller bindings
2
3The GPIO controller should be a child node on an I2C bus,
4see: i2c/i2c.txt for details.
5
6Required properties:
7- compatible: Should be "gateworks,pld-gpio"
8- reg: I2C slave address
9- gpio-controller: Marks the device node as a GPIO controller.
10- #gpio-cells: Should be <2>. The first cell is the gpio number and
11  the second cell is used to specify optional parameters.

13Example:
14
15pld@56 {
16	compatible = "gateworks,pld-gpio";
17	reg = <0x56>;
18	gpio-controller;
19	#gpio-cells = <2>;
20};
