在设备树中创建I2C节点，使用i2c_register_board_info()或i2c_new_device()注册设备，并向驱动程序提供I2C地址和设备ID。示例如下：

static struct i2c_board_info i2c_info = {
    I2C_BOARD_INFO("device_id", 0x01)
};

static void __init my_driver_i2c_init(void)
{
    i2c_register_board_info(0, &i2c_info, 1);
}

static struct i2c_device_id my_driver_i2c_id[] = {
    { "device_id", 0 },
    { }
};
MODULE_DEVICE_TABLE(i2c, my_driver_i2c_id);

static struct i2c_driver my_driver = {
    .driver = {
        .name = "my_driver",
        .owner = THIS_MODULE,
    },
    .probe = my_driver_probe,
    .remove = my_driver_remove,
    .id_table = my_driver_i2c_id,
};

static int my_driver_probe(struct i2c_client *client, const struct i2c_device_id *id)
{
    // 驱动程序的处理逻辑
}

static int my_driver_remove(struct i2c_client *client)
{
    // 驱动程序的卸载逻辑
}

module_i2c_driver(my_driver);
