This AXI port helps to establish the data path between the PS and PL. In-order to establish the proper communication data path between PS and PL the AXI port data path should be configured with the proper Bus-width values. This patch adds the binding document for the zynqmp afi config driver to handle the AXI port bus-width configurations and PS-PL resets.
