    1 Binding for the GPIO extension bus found on some LaCie/Seagate boards
    2 (Example: 2Big/5Big Network v2, 2Big NAS).
    3 
    4 Required properties:
    5 - compatible: "lacie,netxbig-gpio-ext".
    6 - addr-gpios: GPIOs representing the address register (LSB -> MSB).
    7 - data-gpios: GPIOs representing the data register (LSB -> MSB).
    8 - enable-gpio: latches the new configuration (address, data) on raising edge.
    9 
   10 Example:
   11 
   12 netxbig_gpio_ext: netxbig-gpio-ext {
   13         compatible = "lacie,netxbig-gpio-ext";
   14 
   15         addr-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH
   16                       &gpio1 16 GPIO_ACTIVE_HIGH
   17                       &gpio1 17 GPIO_ACTIVE_HIGH>;
   18         data-gpios = <&gpio1 12 GPIO_ACTIVE_HIGH
   19                       &gpio1 13 GPIO_ACTIVE_HIGH
   20                       &gpio1 14 GPIO_ACTIVE_HIGH>;
   21         enable-gpio = <&gpio0 29 GPIO_ACTIVE_HIGH>;
   22 };
