Need Help regarding Linux application using AXI DMA(simple mode) & custom IP (streaming interface))

Hi all,
I am trying to make one linux application(linaro on ARM of Zedboard) where my custom IP (matrix multiplier with streaming interface) is connected to ACP of PS through AXI DMA IP. I will send input data to custom IP from PS and will get the output to PS from custom IP. I am not a person with kernel background knowledge and so I am stuck in this problem. Please suggest me how to proceed for it. If anyone has done work in this field then I earnestly request you to help me out. Should I write driver for AXI DMA as well as my custom IP?? In some threads, I found that there is some issues with AXI DMA driver. So if you have solved it then please share the same.My bare-metal application was successful. Please please help me with valuable suggestions and references.
