adi,tmc2209

Note

An implementation of a driver matching this compatible is available in drivers/stepper/adi_tmc/adi_tmc22xx_stepper_controller.c.

Description

Analog Devices TMC2209 stepper motor driver.

Example:
tmc2209: tmc2209 {
    compatible = "adi,tmc2209";
    enable-gpios = <&gpio0 0 GPIO_ACTIVE_HIGH>;
    msx-gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>,
                <&gpio0 2 GPIO_ACTIVE_HIGH>;
    step-gpios = <&gpio0 3 GPIO_ACTIVE_HIGH>;
    dir-gpios = <&gpio0 4 GPIO_ACTIVE_HIGH>;
    dual-edge-step;
}

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`enable-gpios`	`phandle-array`	GPIO pins used to control the enable signal of the motor driver.
`msx-gpios`	`phandle-array`	An array of GPIO pins for configuring the microstep resolution of the driver. The pins should be listed in the following order: - MS1 - 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`
`step-gpios`	`phandle-array`	The GPIO pins used to send step signals to the stepper motor.
`dir-gpios`	`phandle-array`	The GPIO pins used to send direction signals to the stepper motor. Pin will be driven high for forward direction and low for reverse direction.
