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>;
	};
