Binding for the GPIO extension bus found on some LaCie/Seagate boards

(Example: 2Big/5Big Network v2, 2Big NAS).



Required properties:

- compatible: "lacie,netxbig-gpio-ext".

- addr-gpios: GPIOs representing the address register (LSB -> MSB).

- data-gpios: GPIOs representing the data register (LSB -> MSB).

- enable-gpio: latches the new configuration (address, data) on raising edge.



Example:



netxbig_gpio_ext: netxbig-gpio-ext {

	compatible = "lacie,netxbig-gpio-ext";



	addr-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH

		      &gpio1 16 GPIO_ACTIVE_HIGH

		      &gpio1 17 GPIO_ACTIVE_HIGH>;

	data-gpios = <&gpio1 12 GPIO_ACTIVE_HIGH

		      &gpio1 13 GPIO_ACTIVE_HIGH

		      &gpio1 14 GPIO_ACTIVE_HIGH>;

	enable-gpio = <&gpio0 29 GPIO_ACTIVE_HIGH>;
