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. 12 13Example: 14 15pld@56 { 16 compatible = "gateworks,pld-gpio"; 17 reg = <0x56>; 18 gpio-controller; 19 #gpio-cells = <2>; 20}; 21
