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>; };
