To be more specific, the current answer is this (which is the same as
what's in next-20221213):

  https://git.kernel.org/cgit/linux/kernel/git/helgaas/pci.git/tree/Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml?id=f64171fdd171

If you think it needs to be different, please respond with a patch and
explanation.
