<div>> Thanks Richard. One more question. If I register an SPI irq struct spi_board_info spi_board_info[] structure in machine board.c file; then the request irq api and irq handler<br>
> should be written in board.c file or in the spidev driver.<br>
<br>
</div>Never do any programming in the board file.<br>
The purpose if the board file it describing the hardware.<br>
Please note, board files go away, device tree is the way to go.<br>

Thanks,<br>
