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>;

	};
