  GPIO Stepper Controller for darlington transistor arrays or dual H-bridge

  Example:
    /* Lead A is connected Lead C and Lead B is connected to Lead D*/
    stepper: stepper {
        compatible = "zephyr,gpio-stepper";
        gpios = <&gpioa 9 GPIO_ACTIVE_HIGH>,  /* Lead A1/A */
                <&gpioc 7 GPIO_ACTIVE_HIGH>,  /* Lead B1/B */
                <&gpiob 0 GPIO_ACTIVE_HIGH>,  /* Lead A2/C */
                <&gpioa 7 GPIO_ACTIVE_HIGH>;  /* Lead B2/D */
    };

compatible: "zephyr,gpio-stepper"
