Hi,
quoted
spi_register_board_info() will add the board information structure to board_list in drivers/spi/spi.c. The list is walked from scan_boardinfo() in the same file when a SPI master is registered by spi_register_master(). The first step would be to check if spi_register_master() is called, and if it fails before calling scan_boardinfo(). Add a few printk's there. If a master is correctly registered, scan_boardinfo() will call spi_new_device(), which in turn calls device_register(). That's where the spi_match_device() function should be called, using the function pointer stored in proxy->dev.bus.match.Thank you for your help, is it possible that calling spi_register_master() before the spi_register_board_info() and before the registration for m25p80 spi device causes the problem?
I think it might, but I'm not sure. Try registering the master after registering board information if you can. Laurent Pinchart
