example of using axi_dmac linux device driver from kernel space

We have a picozed-SDR board. It has a AD9361 in it.  We have Linux (ADI image) up and running and able to stream data to and from AD9361.


The ARM communicates with the AD9361_HDL in the FPGA through the AXI_DMAC IP. We found the Linux driver for it here-


Can you please guide or point to some examples of using axi_dmac from Kernel space ? We want to send communication packets  (MAC- PHY) via AXI_DMAC to our custom logic in FPGA.


How are the functions in axi_dma_driver used by LIBIIO user space. I am more on FPGA side, and less on Kernel programming and would appreciate your help (larsc)
