1Gateworks PLD GPIO controller bindings 2 3The GPIO controller should be a child node on an I2C bus. 4 5Required 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 12Example: 13 14pld@56 { 15 compatible = "gateworks,pld-gpio"; 16 reg = <0x56>; 17 gpio-controller; 18 #gpio-cells = <2>; 19}; 20
