+The Zynq Processing System core provides access from PL masters to PS

+-compatible: Should contain "xlnx,zynq-afi-fpga"
+-reg: Physical base address and size of the controller's register area.
+-xlnx,afi-buswidth : Size of the afi bus width.
+ 0: 64-bit AXI data width,
+ 1: 32-bit AXI data width,

+Example:
+afi0: afi0 {
+ compatible = "xlnx,zynq-afi-fpga";
+ reg = <0xf8008000 0x1000>;
