1 * Generic 8-bits shift register GPIO driver 2 3 Required properties: 4 - compatible : Should be "fairchild,74hc595" 5 - reg : chip select number 6 - gpio-controller : Marks the device node as a gpio controller. 7 - #gpio-cells : Should be two. The first cell is the pin number and 8 the second cell is used to specify the gpio polarity: 9 0 = active high 10 1 = active low 11 - registers-number: Number of daisy-chained shift registers 12 13 Example: 14 15 gpio5: gpio5@0 { 16 compatible = "fairchild,74hc595"; 17 reg = <0>; 18 gpio-controller; 19 #gpio-cells = <2>; 20 registers-number = <4>; 21 spi-max-frequency = <100000>; 22 };
