Sorry for the delay.

The main problem with this patch is that it does too many things.
It should be separated into three patches:

1. Convert the driver into a platform driver;
2. Add support for detect gpio;
3. Add retry machanism.

But still, why are you converting the i2c driver into a platform driver?
To pass the GPIOs via platform data? You can do this with I2C driver as
well:

struct i2c_board_info {
        ....
        void            *platform_data;
