i have been using the OPB SPI 1.00.e for a quite a while now in a kernel 2.6.24 with the Xilinx driver. The use was quite straightforward thanks to the spidev interface, everything in userspace. Now we have migrated to 18.104.22.168 and things seem to have changed. So, with the old IP core/Driver we got "spi0" device (/dev/spi0) we could read/write/ioctl but that is not longer availble. The system just doesn't register that device, neither /dev/spidev* or anything like that. Of course now we use a .dts and before we were using a BSP, so I guess things might have changed a bit. Any clue of what should I do to make the kernel register that device?
