Description

TI DRV84XX stepper motor driver.
Compatible with drv8424, drv8425, drv8426, drv8434 and drv8436.

Example:
drv8424: drv8424 {
  status = "okay";
  compatible = "ti,drv84xx";

  fault-gpios = <&arduino_header 16 0>;
  sleep-gpios = <&arduino_header 15 GPIO_ACTIVE_LOW>;
  en-gpios  = <&arduino_header 14 0>;
  m0-gpios = <&mikroe_stepper_gpios 0 0>;
  m1-gpios = <&mikroe_stepper_gpios 1 0>;
};
