i.MX6 EIM driver for FPGA

I'm currently working on a Linux driver for communicating with a FPGA via the EIM port.  I think I have a handle on the EIM configuration, and the people working on the FPGA are fairly open to how we're doing the communication, so I think we have that covered.  What I don't understand very well, as it's different than anything else I've worked on, is the IOMUX configuration.  I've been digging through the chip reference manual, but it's not giving me a lot of insight into how I set this up. Does anyone have any test code or code snippets they would be willing to share?  Maybe an example they found somewhere that helped?  I've looked through the Linux BSP code, and didn't find anything, but might have missed it.  I would have thought there would be some chipset test code somewhere with the BSP, but it's possible that I missed it.  Thanks.
