have you tried testing without specifying the fifo_depth in DT?

You'll probably hit a divide by zero at:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/spi/spi-s3c64xx.c#n664

I assume the controller can work with 0 sized FIFO depth, and if so, the
driver has to be updated to allow 0 sized FIFOs.

btw, how did you test the set?
