Alan, There was a problem with the field IRQ and bus_num. Now, we go through the "probe" function. Thanks a lot, Regards,Emilie.

IRQ is just passed through to the driver (so it's likely not causing _this_ problem), but .bus_num may be causing you a problem. If you look in spi.h, bus_num is a u16, so -EINVAL is never valid for that field. What goes in that field is the SPI bus your device is connected to. On the Beagle Bone, SPI bus number 2 is the one I'm using, and it's labeled SPI1 in the Beagle Bone SRM. Also, I assume that you are checking that spi1_init() is actually getting called. On the board file, look at my patch again (from May 23). That's really all you need to do in the board file. I literally just changed "spidev" to "mrf24j40" to make it start using my driver. You seem to be doing similar things (except for .bus_num). On the driver side, spi_register_driver() with your spi_driver struct should be all that's needed for the SPI subsystem to probe your driver (if your driver is loaded manually with modprobe). Like I said before, setting up the MODULE_DEVICE_TABLE will make the module load automatically.
