Linux/DM3730: Porting old 2.6 GPMC FPGA Driver issues.

Part Number:DM3730

Tool/software: Linux

I am attempting to port a very old 2.6 kernel driver that configured and utilized the GPMC. I am running a 4.14 kernel and I am configuring the GPMC with the device tree. Between the two versions of the driver, all of the CONFIG_i registers match perfectly, so theoretically the driver should be working. All I am trying to do is read/write a scratch register on the FPGA connected to the GPMC. All the settings match, the clocking rates match, etc. Are there any other caveats Porting GPMC drivers from older kernels? Thanks in advance.
