I'm trying to access some IP from the PS on a ZC706 Zynq chip. There doesnt appear to be a driver available for this specific IP (for linux anyway). So I was trying to set it to generic-uio (so I could mmap it) in the DTS file but it doesn't appear under /sys/class/uio. (I've rebuilt and reloaded the kernel)
What is the correct way to change the "compatible" parameter in the DTS file? and which DTS file within the petalinux project should I be changing?
The IP in question is AXI4-Stream FIFO v4.1, it appears to be a xilinx IP. If there's a better way of using the IP from petalinux please point me in the right direction.

It seems that the "compatible" entry was removed in Petalinux 2015.2, so the driver never gets loaded. It worked perfectly in 2014.2.
