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>; |
|
};
