AXI chip2chip external peripherals and the linux device tree

I am using AXI chip2chip between a Zynq and a remote Kintex Ultrascale.  I have multiple peripherals on the bus on the Kintex Ultrascale side.  How do I add those devices to the Linux device tree on the Zynq?  I have looked for examples but can't find any.  The only thing that shows up in the PL side of the Zynq device tree is the chip2chip peripheral.  I want Linux to instantiate the devices/drivers based on the "combined" device tree including the remote devices on the other end of the chip2chip side.

 

I could really use some help.
