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>;
};
