PicoEVB M.2 FPGA on Jetson Nano


I would like to connect the Jetson Nano platform to the PicoEVB FPGA module. The PicoEVB has a SPI controller in it that I would like to enable using the linux devicetree.
Within the linux kernel, I see this file: Documentation/devicetree/bindings/pci/nvidia,tegra20-pcie.txt which contains a note saying that a SPI bus must be described in the devicetree.
Are there any examples of this? The bindings txt file has an example but not one that shows how a SPI/I2C controller would be mapped from something like the PicoEVB.

Any help with this will be much appreciated.

Thank you

Have check below doc for SPI/I2C
