0001 Bindings for the fan / temperature monitor microcontroller used on
0002 the Zyxel NSA 320 and several subsequent models.
0003
0004 Required properties:
0005 - compatible : "zyxel,nsa320-mcu"
0006 - data-gpios : The GPIO pin connected to the data line on the MCU
0007 - clk-gpios : The GPIO pin connected to the clock line on the MCU
0008 - act-gpios : The GPIO pin connected to the active line on the MCU
0009
0010 Example:
0011
0012 hwmon {
0013 compatible = "zyxel,nsa320-mcu";
0014 pinctrl-0 = <&pmx_mcu_data &pmx_mcu_clk &pmx_mcu_act>;
0015 pinctrl-names = "default";
0016
0017 data-gpios = <&gpio0 14 GPIO_ACTIVE_HIGH>;
0018 clk-gpios = <&gpio0 16 GPIO_ACTIVE_HIGH>;
0019 act-gpios = <&gpio0 17 GPIO_ACTIVE_LOW>;
0020 };
