How to Resolve DHT22 Sensor Driver Binding Issue with Zephyr OS on AVR32UC?

Hello guys, I've been working on integrating the DHT22 sensor driver with Zephyr OS on the AVR32UC microcontroller, but currently, I'm struggling with the sensor driver binding. Despite my efforts, I keep encountering the error: Failed to bind DHT22 sensor. Here's a snippet of my code:

#include <zephyr.h>
#include <device.h>
#include <drivers/sensor.h>

const struct device *sensor_dev;

void main(void)
{
    sensor_dev = device_get_binding(DT_LABEL(DT_INST(0, ams_dht22)));
    if (!sensor_dev) {
        printk("Failed to bind DHT22 sensor\n");
        return;
    }
}

#include <zephyr.h>
#include <device.h>
#include <drivers/sensor.h>

const struct device *sensor_dev;

void main(void)
{
    sensor_dev = device_get_binding(DT_LABEL(DT_INST(0, ams_dht22)));
    if (!sensor_dev) {
        printk("Failed to bind DHT22 sensor\n");
        return;
    }
}

I've made sure the DHT22 sensor driver is included and configured in prj.conf, checked the device tree (dts file) for the correct sensor definitions, and verified that the driver is supported and enabled for the AVR32UC. Despite this, I can't seem to get it to bind properly. How can I resolve this issue and successfully bind the DHT22 sensor driver, Anyone?
