Where is the bindings documenting this child node of pcie device?

Can we have generic node name for it?

This is part of the "PCI Bus Binding to: IEEE Std 1275-1994" document,
which is referenced in Documentation/devicetree/bindings/pci/pci.txt.
This is a standard PCIe topology description mapped to DT.

I would like to avoid this if possible. We are sharing the code to
patch in the MAC address from the bootloader with the RDU2, which has
the same node name and the patching code looks for the specific name.

Please resend the patch to include DT and PCI folks and list.
