yes, if you have the proper struct i2c_driver and struct i2c_device_id in
your driver the i2c subsystem should call the probe of your device.
check drivers/i2c/chips/menelaus.c for an example.
See how I2C_BOARD_INFO() in arch/arm/mach-omap2/board-h4
and struct i2c_device_id have the same name for the device (menelaus).

no, i2c layer will call device probe based on the driver name being the same in
i2c_board_info and i2c_device_id (if I'm not wrong that's the match,
Jean correct
me if I'm wrong).

That's old style i2c driver. You don't need that anymore ;-)
