We have to follow the following steps
1. 
    static struct spi_board_info your_board_info[] __initdata = {
    {
    .modalias = "driver_name",
         .....
    }
2. Register your board with: spi_register_board_info()
3. you have to add device to the device table with 
           MODULE_DEVICE_TABLE(spi, your_device_id).
  

    your device id name should be the modalise name that you are providing
in spi_board_info().

These steps may help you.
