Hi Wolfram,
Thank your for the guide.
I have understood your guide.
And I have released version 4 of I2C patch.
Please check it for me.
Thanks,

Yes, this is much better. Only minor things...

Please put the default case block at the end.

This cannot happen. Since you have 'i2c-rcar' in the id_table, the
driver core will always match against the id_table and there is always a
driver_data defined.
+ priv->devtype = pdev->id_entry->driver_data;
Basically the same, but please use
platform_get_device_id(pdev)->driver_data;
Otherwise good!
Thanks,
Wolfram
