Name	Type	Details
step-width-ns	int	Minimum pulse width in nanoseconds for the step signal. Default value: 100
m0-gpios	phandle-array	Microstep configuration pin MS1.
m1-gpios	phandle-array	Microstep configuration pin MS2.
dual-edge-step	boolean	If present, the stepper motor controller supports dual edge step signals. This means that the step signal can be toggled on both the rising and falling edge.
micro-step-res	int	micro-step resolution to be set while initializing the device driver. Default value: 1 Legal values: 1, 2, 4, 8, 16, 32, 64, 128, 256
en-gpios	phandle-array	GPIO pins used to control the enable signal of the motor driver.
