Gratuitous "PCIe" capitalization changes here and in supplies below.
This is just plain English text so we can use English conventions.

I *would* be OK if you dropped the periods at the end of these, which
would make them match the other descriptions in this binding.

I'm not sure about the "tesla,fsd-pcie-ep.yaml" filename.  I see that
it currently only describes a tesla endpoint, but it seems like maybe
this should be parallel to the "samsung,exynos-pcie.yaml" host
controller binding.
