Hi,Rita,

我想请教一下IMX6Q平台I2C设备的client是在哪里创建的？
如\yocto-dev\build\tmp\work\imx6qsabresd-poky-linux-gnueabi\linux-imx\3.10.17-r0\git\drivers\media\platform\mxc\capture\adv7180.c
里面有i2c_add_driver(&adv7180_i2c_driver)，不知i2c_client是在什么地方创建
还有就是这颗IC是在你们哪个型号的开发板上验证过的呢？移植到SABRESD板子上需要改哪些地方？

static const struct i2c_device_id adv7180_id[] = {
      {"adv7180", 0},
      {},
};

MODULE_DEVICE_TABLE(i2c, adv7180_id);

static struct i2c_driver adv7180_i2c_driver = {
      .driver = {
               .owner = THIS_MODULE,
               .name = "adv7180",
               },
      .probe = adv7180_probe,
      .remove = adv7180_detach,
      .id_table = adv7180_id,
};

static __init int adv7180_init(void)
{
      u8 err = 0;

      pr_debug("In adv7180_init\n");

      /* Tells the i2c driver what functions to call for this driver. */
      err = i2c_add_driver(&adv7180_i2c_driver);
      if (err != 0)
            pr_err("%s:driver registration failed, error=%d\n",
                     __func__, err);

      return err;
}
