I2C driver for BMP180

Hi All,

I trying to write I2C client driver for BMP180.

Here is my Code.

#include <linux/module.h>
#include <linux/input.h>
#include <linux/i2c.h>
#include <linux/slab.h>
#include <linux/interrupt.h>

static int bmp_180_i2c_probe(struct i2c_client *client, const struct i2c_device_id *id)
{
        struct i2c_client *my_client = NULL;

        printk("This is I2c Probong Function..\n");

        if (!i2c_check_functionality(client->adapter, I2C_FUNC_I2C)) {
                dev_err(&client->dev, "i2c_check_functionality error\n");
                return -EIO;
        }

        my_client = kzalloc(sizeof(struct i2c_client), GFP_KERNEL);
        if (my_client == NULL) {
                printk(KERN_ERR "%s: no memory\n", __func__);
                return -ENOMEM;
        }

        my_client = client;
        i2c_set_clientdata(client, my_client);

        return 0;
}

static int bmp_180_i2c_remove(struct i2c_client *client)
{
        struct i2c_client *my_client = i2c_get_clientdata(client);

        printk("This is I2c Removing Function..\n");

        kfree(my_client);

        return 0;
}

static const struct i2c_device_id bmp_180_i2c_id[] = {
        { "bmp_180", 1 },
        { },
};

MODULE_DEVICE_TABLE(i2c, bmp_180_i2c_id);

static const struct of_device_id bmp_180_dt_ids[] = {
         { .compatible = "bosch,bmp_180", },
         { }
};
MODULE_DEVICE_TABLE(of, bmp_180_dt_ids);

static struct i2c_board_info bmp_i2c_devices[] __initdata = {
        {
                I2C_BOARD_INFO("bmp_180", 0xEF),
        },
};

static struct i2c_driver bmp_180_i2c_driver = {
        .driver = {
                .name   = "bmp_180",
                .of_match_table = bmp_180_dt_ids,
        },

        .probe          = bmp_180_i2c_probe,
        .remove         = bmp_180_i2c_remove,
        .id_table       = bmp_180_i2c_id,
};
//module_i2c_driver(bmp_180_i2c_driver);

static int __init my_init(void)
{
        //i2c_register_board_info(0, bmp_i2c_devices,ARRAY_SIZE(bmp_i2c_devices));

        struct i2c_client *client;

        struct i2c_adapter *adapter = NULL;

        printk(" BMP I2c Driver inserted to kernel \n");

        i2c_add_driver(&bmp_180_i2c_driver);

        adapter = i2c_get_adapter(2);
                printk("i2c_get_adapter:- %p\n", adapter);
        //if (!adapter) return -EINVAL;


        //client = i2c_new_device(adapter, bmp_i2c_devices);
          //      printk("i2c_new_device:- %p\n", client);
        //if (!client) return -EINVAL;

        printk("This is BMP init\n");

        return 0;
}

static void __exit my_exit(void)
{
        i2c_del_driver(&bmp_180_i2c_driver);

        printk("This is BMP Exit\n");
}

module_init(my_init);
module_exit(my_exit);

MODULE_DESCRIPTION("BMP 180 I2C Driver");
MODULE_AUTHOR("RAHUL GUPTA");
MODULE_LICENSE("GPL");

Output:-

[ 5887.459396]  BMP I2c Driver inserted to kernel
[ 5887.459859]  i2c_get_adapter:- dce88c70
[ 5887.459877] This is BMP init

Problem is that  my probing function is not getting called.

Please guide me, where I am going Wrong.

Thanks Guys
