    1 Bindings for the fan / temperature monitor microcontroller used on
    2 the Zyxel NSA 320 and several subsequent models.
    3 
    4 Required properties:
    5 - compatible    : "zyxel,nsa320-mcu"
    6 - data-gpios    : The GPIO pin connected to the data line on the MCU
    7 - clk-gpios     : The GPIO pin connected to the clock line on the MCU
    8 - act-gpios     : The GPIO pin connected to the active line on the MCU
    9 
   10 Example:
   11 
   12         hwmon {
   13                 compatible = "zyxel,nsa320-mcu";
   14                 pinctrl-0 = <&pmx_mcu_data &pmx_mcu_clk &pmx_mcu_act>;
   15                 pinctrl-names = "default";
   16 
   17                 data-gpios = <&gpio0 14 GPIO_ACTIVE_HIGH>;
   18                 clk-gpios = <&gpio0 16 GPIO_ACTIVE_HIGH>;
   19                 act-gpios = <&gpio0 17 GPIO_ACTIVE_LOW>;
   20         };
