I am looking for an interface AXI (Linux driver) between A53 and FPGA for ZCU102 Rev 1.x board.
I searched github repos and forum but could not locate. Your quick help is sincerely appreciated.

What do you mean "Unix Communication Driver" ?
Did you refer uio driver and mmap ?
If my understanding is correct, you can use uio driver or mmap to achieve what you want to do.

I looking to (communicate) do the data transfer A53 ARM processor to FPGA and vice-e-versa , I have Ubuntu OS on my SD card and looking for device driver which can be called by my file transfer program to transfer data (by passing) OS (using kernel).
If uio and mmap is helpful then I will look at those drivers.
My apologies, I am very new to this Xilinx boards (I've experties in Unix)

I suggest you to use DMA driver in this case.
Would you refer it ?
Also, there are relevant information. Would you refer, too ?
Hope this helps,

Thank you sir..
To simplify my request..
I have a Xilinx Zynq UltraScale+ FPGA with ARM A53 processor board (part number XCZU19EG-2FFVC1760E).
I need a Linux based driver that will allow me to communicate between the A53 processor and the FPGA over the AXI bus.
Please let me know where/how I can get a copy of this driver.

Sorry. I don't understand it.
Did you try kernel config to enable ex. DMA driver by ex. petalinux-config command ?
If no, would you refer this document ?
