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>;
};
