1 Gateworks PLD GPIO controller bindings
2
3 The GPIO controller should be a child node on an I2C bus.
4
5 Required properties:
6 - compatible: Should be "gateworks,pld-gpio"
7 - reg: I2C slave address
8 - gpio-controller: Marks the device node as a GPIO controller.
9 - #gpio-cells: Should be <2>. The first cell is the gpio number and
10 the second cell is used to specify optional parameters.
11
12 Example:
13
14 pld@56 {
15 compatible = "gateworks,pld-gpio";
16 reg = <0x56>;
17 gpio-controller;
18 #gpio-cells = <2>;
19 };
