Kernel-4.18.0-80.el8_gpio-lp3943

TI/National Semiconductor LP3943 GPIO controller

Required properties:

  • compatible: “ti,lp3943-gpio”
  • gpio-controller: Marks the device node as a GPIO controller.
  • #gpio-cells: Should be 2. See gpio.txt in this directory for a
             description of the cells format.
    

Example:
Simple LED controls with LP3943 GPIO controller

&i2c4 {
lp3943@60 {
compatible = “ti,lp3943”;
reg = <0x60>;

    gpioex: gpio {
        compatible = "ti,lp3943-gpio";
        gpio-controller;
        #gpio-cells = <2>;
    };
};

};

leds {
compatible = “gpio-leds”;
indicator1 {
label = “indi1”;
gpios = <&gpioex 9 GPIO_ACTIVE_LOW>;
};

indicator2 {
    label = "indi2";
    gpios = <&gpioex 10 GPIO_ACTIVE_LOW>;
    default-state = "off";
};

};
