This patch adds device tree support for the netxbig LEDs. This also introduces a additionnal DT binding for the GPIO extension bus (netxbig-gpio-ext) used to configure the LEDs. Since this bus could also be used to control other devices, then it seems more suitable to have it in a separate DT binding.

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>;
|
|
};
