Bindings for the fan / temperature monitor microcontroller used on
|
|
the Zyxel NSA 320 and several subsequent models.
|
|
|
|
Required properties:
|
|
- compatible : "zyxel,nsa320-mcu"
|
|
- data-gpios : The GPIO pin connected to the data line on the MCU
|
|
- clk-gpios : The GPIO pin connected to the clock line on the MCU
|
|
- act-gpios : The GPIO pin connected to the active line on the MCU
|
|
|
|
Example:
|
|
|
|
hwmon {
|
|
compatible = "zyxel,nsa320-mcu";
|
|
pinctrl-0 = <&pmx_mcu_data &pmx_mcu_clk &pmx_mcu_act>;
|
|
pinctrl-names = "default";
|
|
|
|
data-gpios = <&gpio0 14 GPIO_ACTIVE_HIGH>;
|
|
clk-gpios = <&gpio0 16 GPIO_ACTIVE_HIGH>;
|
|
act-gpios = <&gpio0 17 GPIO_ACTIVE_LOW>;
|
|
};
