| 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>;
 | |
| };
