1Binding for the GPIO extension bus found on some LaCie/Seagate boards
2(Example: 2Big/5Big Network v2, 2Big NAS).
3
4Required 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.

10Example:
11
12netxbig_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>;
