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.
