Hi I am Gwangho Choi, I am trying to connect my EVAL-AD5791 board with a raspberry pi 3 b+ using iio. I enabled SPI from raspi-config. And I made an ad5791 module from a kernel and loaded. Now, I can see ad5791 and industialio module running from "lsmod" command. And I can also see the /sys/bus/iio/ directory.So, I connected my board with my raspberry pi, but in the /sys/bus/iio/devices there is nothing. I suspect that I did not declare a slave device, but I do not know how I can do it. I do not know where I should put the spi_board_info code. I cannot find arch/.../mach-*/board-*.c files. Thanks
